Coupling of a whispering gallery mode to a silicon chip with photonic crystal
Yuyang Zhuang, Hajime Kumazaki, Shun Fujii +5
We demonstrate the efficient coupling (99.5%) of a silica whispering gallery mode microresonator directly with a silicon chip by using a silicon photonic crystal waveguide as a cou…

Octave-wide phase-matched four-wave mixing in dispersion engineered crystalline microresonators
Shun Fujii, Shuya Tanaka, Mika Fuchida +5
In this Letter, we report phase-matched four-wave mixing separated by over one-octave in a dispersion engineered crystalline microresonator. Experimental and numerical results pres…
