Optical design of split-beam photonic crystal nanocavities.
We design high-quality-factor photonic crystal nanobeam cavities formed by two mechanically isolated cantilevers. These "split-beam" cavities have a physical gap at the center, allowing mechanical excitations of one or both of the cavity halves. They are designed by analyzing the optical band structures and mode profiles of waveguides perforated by elliptical holes and rectangular gaps and are ...
متن کاملDesign of photonic band gap nanocavities for stimulated Raman amplification and lasing in monolithic silicon.
The concept and design of L5 photonic band gap nanocavities in two-dimensional photonic crystal slabs for enhancement of stimulated Raman amplification and lasing in monolithic silicon is suggested for the first time. Specific high quality factor and small modal volume nanocavities are designed which supports the required pump-Stokes modal spacing in silicon, with ultralow lasing thresholds.
متن کاملStimulated Raman amplification and lasing in silicon photonic band gap nanocavities
The concept and design of L5 photonic band gap nanocavities in two-dimensional (2D) photonic crystal (PhCs) slabs for enhancement of timulated Raman amplification and lasing in monolithic silicon is suggested for the first time. Specific high quality factor (Q) and small modal olume nanocavities are designed which supports the required pump–Stokes modal spacing in silicon, with ultra-low lasing...
متن کاملUltra-high-Q TE/TM dual-polarized photonic crystal nanocavities.
We demonstrate photonic crystal nanobeam cavities that support both TE- and TM-polarized modes, each with a Q factor greater than one million and a mode volume on the order of the cubic wavelength. We show that these orthogonally polarized modes have a tunable frequency separation and a high nonlinear spatial overlap. We expect these cavities to have a variety of applications in resonance-enhan...
متن کاملThe New Method for Optical Channel Drop Filter with High Quality Factor Based on Triangular Photonic Crystal Design
We have designed a new type of optical channel drop filter (CDF) based on two dimensionaltriangular lattice photonic crystals. CDF operation is based on coupling to the photonic crystalwaveguide. The proposed structure is optimized to work as a CDF for obtaining the CDFcharacteristics and band structure of the filter the finite difference time domain (FDTD) method andplane wave expansion (PWE) ...
