Watt-class CMOS-compatible power amplifier
Neetesh Singh, Jan Lorenzen, Kai Wang +8
Power amplifier is becoming a critical component for integrated photonics as the integrated devices try to carve out a niche in the world of real-world applications of photonics. T…
Chip-scale, CMOS-compatible, high energy passively Q-switched laser
Neetesh Singh, Jan Lorenzen, Milan Sinobad +13
Chip-scale, high-energy optical pulse generation is becoming increasingly important as we expand activities into hard to reach areas such as space and deep ocean. Q-switching of th…
Low phase noise THz generation from a fiber-referenced Kerr microresonator soliton comb
Naoya Kuse, Kenji Nishimoto, Yu Tokizane +5
THz oscillators generated via frequency-multiplication of microwaves are facing difficulty in achieving low phase noise. Photonics-based techniques, in which optical two tones are…
Frequency-scanned microresonator soliton comb with the tracking of the frequency of all comb modes
Naoya Kuse, Gabriele Navickaite, Michael Geiselmann +2
Rapid and large scanning of a dissipative Kerr-microresonator soliton comb with the characterization of all comb modes along with the separation of the comb modes is imperative for…
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…
