Microcomb-referenced photonic stabilization of resonant tunneling diode terahertz oscillators
Miezel Talara, Yu Tokizane, Tatsunoshin Mori +7
We demonstrate a compact stabilization scheme for terahertz (THz) sources by exploiting the complementary advantages of microresonator-based optical frequency combs (microcombs) an…
All-photonic W-band terahertz receiver based on THz-to-optical carrier conversion with soliton microcomb dual carriers for high-speed OOK wireless transmission
Yudai Matsumura, Hiroki Kishikawa, Naoya Kuse +11
We demonstrate an all-photonic terahertz receiver for a data-modulated signal, targeting a 106-GHz, 2.97-Gb/s OOK link. The scheme employs dual-wavelength optical carriers referenc…
Laser-scanning optical-frequency-comb microscopy for multimodal imaging
Shimpei Kajiwara, Eiji Hase, Shota Nakano +9
We introduce a novel laser-scanning optical microscopy technique that employs optical-frequency-comb (OFC) lasers. This method facilitates multimodal spectroscopic imaging by analy…
Reduction of temperature drift in refractive-index-sensing optical frequency comb by active-dummy compensation of dual-comb configuration
Shogo Miyamura, Masayuki Higaki, Shuji Taue +5
Refractive-index (RI) sensing plays a pivotal role in various domains, encompassing applications like glucose sensing, biosensing, and gas detection. Despite the advantages of opti…
