Design of a passively mode-locking whispering gallery mode microaser
Tomoki S. L. Prugger Suzuki, Ayata Nakashima, Keigo Nagashima +6
Ultrahigh repetition rate lasers will become vital light sources for many future technologies; however, their realization is challenging because the cavity size must be minimized.…

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…
