mid-infrared frequency comb generation and stabilization with few-cycle pulses
Alexander J. Lind, Abijith Kowligy, Henry Timmers +5
Mid-infrared laser frequency combs are compelling sources for precise and sensitive metrology with applications in molecular spectroscopy and spectro-imaging. The infrared atmosphe…
Tunable mid-infrared generation via wide-band four wave mixing in silicon nitride waveguides
Abijith Kowligy, Daniel Hickstein, Alex Lind +8
We experimentally demonstrate wide-band (>100 THz) frequency down-conversion of near-infrared (NIR) femtosecond-scale pulses from an Er:fiber laser to the mid-infrared (MIR) using…
Heterogeneously integrated GaAs waveguides on insulator for efficient frequency conversion
Lin Chang, Andreas Boes, Xiaowen Guo +12
Tremendous scientific progress has been achieved through the development of nonlinear integrated photonics. Prominent examples are Kerr-frequency-comb generation in micro-resonator…
Deuterated silicon nitride photonic devices for broadband optical frequency comb generation
Jeff Chiles, Nima Nader, Daniel D. Hickstein +9
We report and characterize low-temperature, plasma-deposited deuterated silicon nitride thin films for nonlinear integrated photonics. With a peak processing temperature less than…
Mid-infrared frequency comb generation via cascaded quadratic nonlinearities in quasi-phase-matched waveguides
Abijith S. Kowligy, Alex Lind, Daniel D. Hickstein +7
We experimentally demonstrate a simple configuration for mid-infrared (MIR) frequency comb generation in quasi-phase-matched lithium niobate waveguides using the cascaded-…
