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…
Continuous scanning of a dissipative Kerr-microresonator soliton comb for broadband, high resolution spectroscopy
Naoya Kuse, Tomohiro Tetsumoto, Gabriele Navickaite +2
Dissipative Kerr-microresonator soliton combs (hereafter called soliton combs) are promising to realize chip scale integration of full soliton comb systems providing high precision…
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…
