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…
Broadband gain induced Raman comb formation in a silica microresonator
Ryo Suzuki, Akihiro Kubota, Atsuhiro Hori +2
A high-Q silica whispering-gallery mode microresonator is an attractive platform on which to demonstrate a broad and phase-locked Raman comb in various wavelength regimes. Raman co…
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…
Harmonic mode locking in a high-Q whispering gallery mode microcavity
Takumi Kato, Tomoya Kobatake, Ryo Suzuki +2
A numerical and experimental study of the generation of harmonic mode locking in a silica toroid microcavity is presented. We use a generalized mean-field Lugiato-Lefever equation…
Whispering gallery modes in hexagonal microcavities fabricated by crystal growth
Hiroshi Kudo, Ryo Suzuki, Takasumi Tanabe
We investigated the whispering gallery modes of cavities with a hexagonal cross-section. We found two different modes, namely perturbed and quasi-WGMs, of which the former exhibits…
