Kerr-Microresonator Soliton Frequency Combs at Cryogenic Temperatures [PDF]

Physical Review Applied, 2019
We present measurements of silicon nitride nonlinear microresonators and frequency comb generation at cryogenic temperatures as low as 7~K. The resulting two orders of magnitude reduction in the thermo-refractive coefficient relative to room-temperature enables direct access to single bright Kerr soliton states through adiabatic frequency tuning of the

Dual-pump Kerr Micro-cavity Optical Frequency Comb with varying FSR spacing [PDF]

, 2016
In this paper, we demonstrate a novel dual-pump approach to generate robust optical frequency comb with varying free spectral range (FSR) spacing in a CMOS-compatible high-Q micro-ring resonator (MRR).

Aluminum nitride as nonlinear optical material for on-chip frequency comb generation and frequency conversion

Nanophotonics, 2016
A number of dielectric materials have been employed for on-chip frequency comb generation. Silicon based dielectrics such as silicon dioxide (SiO2) and silicon nitride (SiN) are particularly attractive comb materials due to their low optical loss and ...

Optical frequency synthesis using a dual-Kerr-microresonator frequency comb [PDF]

, 2017
We report a photonic-chip optical-frequency synthesizer using interlocking 1 THz and 22 GHz Kerr microcombs, which provide f-2f self-referencing and a dense comb spanning the C-band, respectively.

A Comparative Analysis on Fully Integrated Spectral Broadening of Kerr Frequency Combs

IEEE Photonics Journal, 2017
Microresonator-based frequency combs have potential to achieve on-chip frequency metrology. To obtain high-power comb lines at f and 2f for self-referenced stabilization, we evaluate the feasibility of building a fully integrated comb generator with ...
