Inverse design of nanophotonic structures using complementary convex optimization
Jesse Lu, Jelena Vuckovic
A computationally-fast inverse design method for nanophotonic structures is presented. The method is based on two complementary convex optimization problems which modify the dielec…
Second harmonic generation in gallium phosphide photonic crystal nanocavities with ultralow continuous wave pump power
Kelley Rivoire, Ziliang Lin, Fariba Hatami +2
We demonstrate second harmonic generation in photonic crystal nanocavities fabricated in the semiconductor gallium phosphide. We observe second harmonic radiation at 750 nm with in…
Photonic Crystal Cavities in Silicon Dioxide
Yiyang Gong, Jelena Vuckovic
One dimensional nano-beam photonic crystal cavities fabricated in silicon dioxide are considered in both simulation and experiment. Quality factors of over 10^4 are found via simul…
Enhanced Light Emission from Erbium Doped Silicon Nitride in Plasmonic Metal-Insulator-Metal Structures
Yiyang Gong, Selcuk Yerci, Rui Li +2
Plasmonic gratings and nano-particle arrays in a metal-insulator-metal structures are fabricated on an erbium doped silicon nitride layer. This material system enables simple fabri…
Electrically controlled modulation in a photonic crystal nanocavity
Dirk Englund, Bryan Ellis, Elizabeth Edwards +4
We describe a compact modulator based on a planar photonic crystal nanocavity whose resonance is electrically controlled. A forward bias applied across a p-i-n diode shifts the cav…
Local temperature control of photonic crystal devices via micron-scale electrical heaters
Andrei Faraon, Jelena Vuckovic
We demonstrate a method to locally control the temperature of photonic crystal devices via micron-scale electrical heaters. The method is used to control the resonant frequency of…
