Slow-light dispersion in coupled periodic waveguides.

2008

Schlüsselwörter: Waveguides; Photonic integrated circuits; Photonic crystals

Zusammenfassung: Periodic waveguides bring a new twist to the typical waveguiding problems of the intermediate case between photonic crystal waveguides and photonic wires or ridge waveguides. We develop an asymptotic theory applicable for a broad class of coupled periodic waveguide structures and use the analytical expressions to identify the generic types of dispersion in the vicinity of a photonic band edge, where the group velocity of light is reduced. We show that the dispersion can be controlled by the longitudinal shift between the waveguides. We also demonstrate through finite-difference time-domain simulations examples of spatial and temporal pulse dynamics in association with different types of slow-light dispersion.

Dispersionless tunneling of slow light in antisymmetric photonic crystal couplers.
Opt. Express, 16(2):1104-1114
2008

Zusammenfassung: We suggest a novel and general approach to the design of photonic-crystal directional couplers operating in the slow-light regime. We predict, based on a general symmetry analysis, that robust tunneling of slow-light pulses is possible between antisymmetrically coupled photonic crystal waveguides. We demonstrate, through Bloch mode frequency-domain and finite-difference time-domain (FDTD) simulations that, for all pulses with strongly reduced group velocities at the photonic band-gap edge, complete switching occurs at a fixed coupling length of just a few unit cells of the photonic crystal.

Coupled nanopillar waveguides optical properties and applications.
Phys. Status Solidi A-Appl. Mat, 204(11):3647-3661
2007

Zusammenfassung: In this paper we review basic properties of coupled periodic and aperiodic nanopillar waveguides. A coupled nanopillar waveguide consists of several rows of periodically or aperiodically placed dielectric rods (pillars). In such a waveguide, light confinement is due to the total internal reflection, while guided modes dispersion is strongly affected by the waveguide structure. We present a systematic analysis of the optical properties of coupled nanopillar waveguides and discuss their possible applications for integrated optics.

Numerical modelling of lasing in microstructures.
Phys. Status Solidi B-Basic Solid State Phys, 244(10):3515-3527
2007

Zusammenfassung: Two methods suitable for numerical modelling of microlasers (including photonic crystal, microcavity, and random lasers) are presented. Finite-difference time-domain (FDTD) method and a generalized coupled mode theory are discussed in the context of microstructured resonators. The cases of one mode and two modes with near-identical properties but different frequencies are investigated in detail. The predictions of the coupled mode model are compared to FDTD simulations of a microcavity laser based on a single defect and twin coupled defects in a photonic crystal lattice. Different regimes of the mode competition (simultaneous and bistable lasing) are analyzed.

Out-of-phase coupled periodic waveguides: a "couplonic" approach.

Schlüsselwörter: couplonics; coupled-mode theory; coupled periodic waveguides; transfer matrix; scattering parameters

Zusammenfassung: We investigate the properties of out-of-phase coupled periodic waveguides (CPW) in the frame of a rigorous coupled-mode theory (CMT), with special emphasis on internal symmetries at the scale of a unit cell. Specifically, we demonstrate an exact mathematical equivalence between the continuously distributed system and its discrete counterpart, made of four-port networks interconnected by segments of transmission lines.

Polariton bandstructure of disordered metallic photonic crystal slabs.
Phys. Status Solidi B-Basic Solid State Phys, 244(4):1262-1269
2007

Zusammenfassung: We analyze the influence of disorder on the polaritonic bandstructure of metallic photonic crystal slabs. Different disorder types with varying next-neighbor correlations and disorder amounts are implemented. Angle-resolved transmission measurements allow to determine the relation of bandstructure and disorder. We found that uncorrelated disorder retains the bandstructure and only reduces the splitting between the gaps. Correlated disorder, however, leads to the complete destruction of the bandstructure for moderate disorder amounts due to the excitation of different modes. We present a model that shows a good agreement with the measurements.

Selective lasing in multimode periodic and non-periodic nanopillar waveguides
Phys. Status Solidi B-Basic Solid State Phys, 244(4):1211-1218
2007

Zusammenfassung: The lasing action in coupled multiple-row periodic and fractal Cantor-like nanopillar waveguides has been numerically investigated. It had been shown earlier [D. N. Chigrin et al., Opt. Express 12, 617 (2004)] that such a system exhibits band splitting with distinct, straightforward and controllable supermode formation. In this paper we demonstrate that selective lasing into each of the supermodes is possible. The structure acts as a microlaser with selectable wavelength. Mode selection is achieved by means of coaxial injection seeding with a Gaussian signal with different transverse envelope. The proposed concept of switchable lasing is viewed as an alternative to conventional laser tuning by means of external cavity control.

Switchable lasing in multimode microcavities.
Phys. Rev. Lett., 99(7):073902
2007

Zusammenfassung: We propose the new concept of a switchable multimode microlaser. As a generic, realistic model of a multimode microresonator a system of two coupled defects in a two-dimensional photonic crystal is considered. We demonstrate theoretically that lasing of the cavity into one selected resonator mode can be caused by injecting an appropriate optical pulse at the onset of laser action (injection seeding). Temporal mode-to-mode switching by reseeding the cavity after a short cooldown period is demonstrated by direct numerical solution. A qualitative analytical explanation of the mode switching in terms of the laser bistability is presented.

Low-loss resonant modes in deterministically aperiodic nanopillar waveguides.
J. Opt. Soc. Am. B-Opt. Phys, 23(10):2265-2272
2006

Zusammenfassung: Quasiperiodic Fibonacci-like and fractal Cantor-like single- and multiple-row nanopillar waveguides are investigated theoretically by employing the finite-difference time-domain method. It is shown that resonant modes of the Fibonacci and Cantor waveguides can have a Q factor comparable with that of a point-defect resonator embedded in a periodic nanopillar waveguide, while the radiation is preferably emitted into the waveguide direction, thus improving coupling to an unstructured dielectric waveguide located along the structure axis. This is especially so when the dielectric waveguide introduces a small perturbation in the aperiodic structure, breaking the structure symmetry while staying well apart from the main localization area of the resonant mode. The high-Q factor and increased coupling with the external dielectric waveguide suggest using the proposed deterministically aperiodic nanopillar waveguides in photonic integrated circuits.

Numerical characterization of nanopillar photonic crystal waveguides and directional couplers.
Opt. Quantum Electron, 37:331-341
2005

Schlüsselwörter: directional couplers; nanoscale photonics; photonic crystal waveguides; transmission

Zusammenfassung: We numerically characterize a novel type of a photonic crystal waveguide, which consists of several rows of periodically arranged dielectric cylinders. In such a nanopillar photonic crystal waveguide, light confinement is due to the total internal reflection. A nanopillar waveguide is a multimode waveguide, where the number of modes is equal to the number of rows building the waveguide. The strong coupling between individual waveguides leads to the proposal of an ultrashort directional coupler based on nanopillar waveguides. We present a systematic analysis of the dispersion and transmission efficiency of nanopillar photonic crystal waveguides and directional couplers. Plane wave expansion and finite difference time domain methods were used to characterize numerically nanopillar photonic crystal structures both in two- and three-dimensional spaces.

Photonic quasicrystals for application in WDM systems.
Phys. Status Solidi A-Appl. Mat., 202(6):997-1001
2005

Zusammenfassung: Photonic quasicrystals can possess an isotropic (complete) photonic bandgap even in the case of low refractive indices of the constitutive materials, which makes them attractive optical materials with important technological applications. In this work, several aspects related to the design of waveguides and cavities using the two-dimensional (2D) octagonal quasiperiodic lattice are investigated numerically. As an example, the integration of waveguides and a resonating cavity to design an add/drop filter for wavelength division multiplexing applications is briefly described.
