Dual terahertz frequency combs for photonic RF readout of refractive index sensing with frequency multiplication and active-dummy temperature compensation
Masayuki Higaki, Yoshiaki Nakajima, Shuji Taue +4
We present a unified refractive index (RI) sensing platform that integrates THz-comb-based frequency multiplication with dual-comb active-dummy temperature compensation. In convent…
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…
Jones-matrix dual-comb spectroscopic polarimetry
Hidenori Koresawa, Hiroki Kitahama, Shogo Tanimura +6
Spectroscopic polarimetry (SP) is a powerful tool for evaluation of thin film, optical materials, and biological samples because it can provide both polarimetric and spectroscopic…
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…
Beyond 350 GHz: Single-channel 112 Gbps photonic wireless transmission at 560 GHz using soliton microcombs
Yu Tokizane, Hiroki Kishikawa, Takumi Kikuhara +11
Sixth-generation (6G) back-haul links will require terahertz (THz) carriers above 350 GHz to escape the congested 300 GHz band and support >100 Gbps data rates. Photonic THz transm…
Direct fiber-coupled soliton microcomb system with enhanced stability and reproducibility via high numerical-aperture polarization-maintaining single-mode fibers and temperature control
Miezel Talara, Yu Tokizane, Kodai Yamaji +6
We propose a compact and robust system architecture for soliton microcomb generation, based on two key techniques: direct fiber coupling using high numerical-aperture polarization-…
