Record-high-Q AMTIR-1 microresonators for mid- to long-wave infrared nonlinear photonics
Liu Yang, Ryo Sugano, Ryomei Takabayashi +6
AMTIR-1 chalcogenide glass has shown its potential for use in thermal imaging systems owing to its low refractive index, thermal resistance and high transparency across the infrare…
Architecture for coherent dual-comb spectroscopy and low-noise photonic microwave generation using mechanically actuated soliton microcombs
Tatsuki Murakami, Koshiro Wada, Soma Kogure +8
Dissipative Kerr soliton microcombs have inspired various intriguing applications such as spectroscopy, ranging, telecommunication, and high purity microwave generation. Mechanical…
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…
