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…
Infrared electric-field sampled frequency comb spectroscopy
Abijith S. Kowligy, Henry Timmers, Alex Lind +5
Molecular spectroscopy in the mid-infrared portion of the electromagnetic spectrum (3--25 um) has been a cornerstone interdisciplinary analytical technique widely adapted across th…
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…
Self-organized nonlinear gratings for ultrafast nanophotonics
Daniel D. Hickstein, David R. Carlson, Haridas Mundoor +7
Modern nonlinear optical materials allow light of one wavelength be efficiently converted into light at another wavelength. However, designing nonlinear optical materials to operat…
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…
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-…
