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…
300 GHz wireless link based on an integrated Kerr soliton comb
Tomohiro Tetsumoto, Antoine Rolland
A Kerr microresonator frequency comb has enabled the generation of low-phase-noise millimeter- and terahertz-waves in conjunction with an ultrafast photodiode. It is intriguing to…
Dissipative Kerr soliton photonic terahertz oscillator referenced to a molecule
James Greenberg, Brendan M. Heffernan, Tomohiro Tetsumoto +1
Controlling the coherence between light and matter has enabled the radiation of electromagnetic waves with spectral purity and stability that defines the Système International (SI)…
Effects of a quiet point on a Kerr microresonator frequency comb
Tomohiro Tetsumoto, Jie Jiang, Martin E. Fermann +3
A quiet point, an operating point of pump-resonance detuning that minimizes frequency fluctuation due to nonlinear effects inside a resonator, has been employed for phase noise red…
300 GHz wave with attosecond-level timing noise
Tomohiro Tetsumoto, Tadao Nagatsuma, Martin E. Fermann +3
Optical frequency division (OFD) via optical frequency combs (OFC) has enabled a leap in microwave metrology leading to noise performance never explored before. Extending the metho…
300 GHz generation based on a Kerr microresonator frequency comb stabilized to a low noise microwave reference
Tomohiro Tetsumoto, Fumiya Ayano, Mark Yeo +3
In this letter, we experimentally demonstrate low noise 300GHz wave generation based on a Kerr microresonator frequency comb operating in soliton regime. The spectral purity of a 1…
Brillouin lasing in coupled silica toroid microcavities
Yoshihiro Honda, Wataru Yoshiki, Tomohiro Tetsumoto +4
We demonstrate stimulated Brillouin scattering (SBS) lasing in a strongly coupled microcavity system. By coupling two silica toroid microcavities, we achieve large mode splitting o…
High-Q coupled resonances on a PhC waveguide using a tapered nanofiber with high coupling efficiency
Tomohiro Tetsumoto, Yuta Ooka, Tanabe Takasumi
We experimentally demonstrate high-Q cavity formation at an arbitrary position on a silicon photonic crystal waveguide by bringing a tapered nanofiber into contact with the surface…
High-Q silica zipper cavity for optical radiation pressure driven MOMS switch
Tomohiro Tetsumoto, Takasumi Tanabe
We design a silica zipper cavity that has high optical and mechanical Q (quality factor) values and demonstrate numerically the feasibility of a radiation pressure driven micro opt…
