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.…
Ultrahigh-Q crystalline microresonator fabrication with only precision machining
Shun Fujii, Yuka Hayama, Kosuke Imamura +3
The development of ultrahigh quality factor (Q) microresonators has been driving such technologies as cavity quantum electrodynamics (QED), high-precision sensing, optomechanics, a…
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…
Transition between Kerr comb and stimulated Raman comb in a silica whispering gallery mode microcavity
Shun Fujii, Takumi Kato, Ryo Suzuki +2
We theoretically and experimentally investigated the transition between modulation instability and Raman gain in a small silica microcavity with a large free-spectral range (FSR),…
The effect on Kerr comb generation in a clockwise and counter-clockwise mode coupled microcavity
Shun Fujii, Atsuhiro Hori, Takumi Kato +5
We study the impact of inherent mode coupling between clockwise (CW) and counter-clockwise (CCW) modes on Kerr comb generation in a small whispering-gallery mode microcavity. Our n…
