Photonic-crystal microresonator-based LiDAR engine
Kenji Nishimoto, Alexander E. Ulanov, Thibault Wildi +1
Self-injection-locked (SIL) narrow-linewidth lasers based on high-Q microresonators are promising sources for frequency-modulated continuous-wave (FMCW) LiDAR, but the SIL mechanis…
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…
Self-cooling, blue-detuned dissipative Kerr microresonator soliton comb
Kenji Nishimoto, Kaoru Minoshima, Naoya Kuse
Dissipative Kerr solitons (DKSs) generated in high-Q microresonators driven by continuous-wave (CW) lasers provide chip-scale optical frequency combs composed of mutually coherent…
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-…
Wireless data transmission in a 560-GHz band using low-phase-noise terahertz wave generated by photomixing of a pair of distributed feedback lasers injection-locking to Kerr micro-resonator soliton comb
Yu Tokizane, Shota Okada, Takumi Kikuhara +12
The demand for higher data rates in next-generation mobile wireless communication systems (6G) has led to significant interest in terahertz (THz) waves as a high-frequency, broad m…
