چکیده

We study experimentally an electrically pumped GaAs-based bandgap structure based on a vertical cavity surface emitting laser (VCSEL). We demonstrate that a microcavity embedded into this bandgap VCSEL structure supports localized optical modes without any holding beam. We propose a model of surface-structured VCSELs based on a reduced dissipative wave equation for describing electromagnetic modes in such semiconductor cavities and analyze a crossover between linear and nonlinear solitonlike cavity modes.

Coupled optical microcavities in one-dimensional photonic bandgap structures

We present a detailed theoretical and experimental study of the evanescent coupled optical microcavity modes in one-dimensional photonic bandgap structures. The coupled-cavity samples are fabricated by depositing alternating hydrogenated amorphous silicon nitride and silicon oxide layers. Splitting of the eigenmodes and formation of a defect band due to interaction between the neighbouring loca...

Invited to the Session: "Advances in FDTD" organized by Dr. S. C. Hagness in PIERS 2000 MODELING OF PHOTONIC BANDGAP (PBG) DEVICES USING MRTD ADAPTIVE SCHEMES

Photonic crystals are periodic dielctric or metallic materials that have the property to forbid the propagation for the electromagnetic waves whose frequency is included within their frequency bandgap. This frequency bandgap depends on the permittivity of the dielectric materials used, their dimensions, their periodicity, and the incidence angle of the electromagnetic waves. Another well-known ...

Design of photonic crystal microcavities for cavity QED.

We discuss the optimization of optical microcavity designs based on two-dimensional photonic crystals for the purpose of strong coupling between the cavity field and a single neutral atom trapped within a hole. We present numerical predictions for the quality factors and mode volumes of localized defect modes as a function of geometric parameters, and discuss some experimental challenges relate...

Field representation for optical defect resonances in multilayer microcavities using quasi-normal modes

Quasi-Normal Modes are used to characterize transmission resonances in 1D optical defect cavities and the related field approximations. We specialize to resonances inside the bandgap of the periodic multilayer mirrors that enclose the defect cavities. Using a template with the most relevant QNMs a variational principle permits to represent the field and the spectral transmission close to resona...

Adjustable Plasmonic Bandgap in One-Dimensional Nanograting Based on Localized and Propagating Surface Plasmons

Compared to the long history of plasmonic gratings, there are only a few studies regarding the bandgap in the propagation of plasmonic surface waves. Considering the previous studies on interpretation of plasmonic bandgap formation, we discuss this phenomenon using the effect of both surface plasmon polariton (SPP) and localized surface plasmon (LSP) for our fabricated one-dimensional metallic-...
