Genetic Optimization of Photonic Bandgap Structures
Joel Goh, Ilya Fushman, Dirk Englund +1
We investigate the use of a Genetic Algorithm (GA) to design a set of photonic crystals (PCs) in one and two dimensions. Our flexible design methodology allows us to optimize PC st…
Ultra Fast Nonlinear Optical Tuning of Photonic Crystal Cavities
Ilya Fushman, Edo Waks, Dirk Englund +3
We demonstrate fast (up to 20 GHz), low power (5 ) modulation of photonic crystal (PC) cavities in GaAs containing InAs quantum dots. Rapid modulation through blue-shifting of…
Efficient Photonic Crystal Cavity-Waveguide Couplers
Andrei Faraon, Edo Waks, Dirk Englund +2
Coupling of photonic crystal (PC) linear three-hole defect cavities (L3) to PC waveguides is theoretically and experimentally investigated. The systems are designed to increase the…
General Recipe for Designing Photonic Crystal Cavities
Dirk Englund, Ilya Fushman, Jelena Vuckovic
We describe a general recipe for designing high-quality factor (Q) photonic crystal cavities with small mode volumes. We first derive a simple expression for out-of-plane losses in…
Coupling of PbS Quantum Dots to Photonic Crystal Cavities at Room Temperature
Ilya Fushman, Dirk Englund, Jelena Vuckovic
We demonstrate the coupling of PbS quantum dot emission to photonic crystal cavities at room temperature. The cavities are defined in 33% Al, AlGaAs membranes on top of oxidized Al…
