Andrew J. Metcalf, Tyler Anderson, Chad F. Bender, Wesley Brand, David Carlson, Scott Diddams, Connor Fredrick, S. Halverson, Daniel D. Hickstein, Fred Hearty, Jeffrey M. Jennings, Shubham Kanodia, Kyle Kaplan, Emily Lubar, Suvrath Mahadevan, Andrew Monson, Joe P. Ninan, Colin Nitroy, Scott Papp, L. Ramsey, Paul Robertson, Arpita Roy, Christian Schwab, Kartik Srinivasan, Gudmundur Stefansson, Ryan C. Terrien
We detail the first infrared precision astronomical spectroscopy results from the combination of an electro-optic laser frequency comb and the Habitable Zone Planet Finder spectrograph at the 10 m Hobby-Eberly telescope.

An electro-optic ultrafast light source with sub-cycle stability

August 8, 2018
Author(s)
David R. Carlson, Daniel D. Hickstein, Wei Zhang, Andrew J. Metcalf, Franklyn J. Quinlan, Scott A. Diddams, Scott B. Papp
Optical frequency combs can produce femtosecond light pulses with sub-cycle precision, and are typically made by relying on the intrinsic stability of mode-locked lasers. Now, by carving a continuous-wave laser into pulses via electro-optic modulation (EOM

Thermal and Nonlinear Dissipative-Soliton Dynamics in Kerr Microresonator Frequency Combs

August 8, 2018

Jordan R. Stone, Travis Briles, Tara E. Drake, Daryl T. Spencer, David R. Carlson, Scott A. Diddams, Scott B. Papp
We report on radiofrequency techniques to reliably generate and control dissipative-Kerr- soliton microresonator frequency combs. Since the pump-laser frequency detuning to the resonator primarily determines the soliton dynamics, we devise an offset Pound

Dual-comb interferometry via repetition-rate switching of a single frequency comb

July 24, 2018
Author(s)
David R. Carlson, Daniel D. Hickstein, Daniel C. Cole, Scott A. Diddams, Scott B. Papp
We experimentally demonstrate a versatile technique for performing dual-comb interferometry using a single frequency comb. By rapid switching of the repetition rate, the output pulse train can be delayed and heterodyned with itself to produce

Theory of Kerr Frequency Combs in Fabry-Perot resonators

July 18, 2018
Author(s)
Daniel C. Cole, Alessandra Gatti, Scott B. Papp, Franco Prati, Luigi Luigato
We derive a spatiotemporal equation describing nonlinear optical dynamics in Fabry-Perot (FP) cavities filled with a Kerr medium. This equation is an extension of the equation that describes dynamics in Kerr-nonlinear ring resonators, referred to as the

Accurate optical stabilization of a Kerr-microresonator frequency comb

Travis Briles, Jordan R. Stone, Tara E. Drake, Daryl T. Spencer, Connor D. Fredrick, Qing Li, Daron A. Westly, Bojan R. Ilic, Kartik A. Srinivasan, Scott A. Diddams, Scott B. Papp
Carrier-envelope-phase stabilization of optical waveforms enables exquisitely precise measurements by way of direct optical-frequency synthesis, coherent optical-to-microwave phase conversion, and control of ultrafast waveforms. We report such phase

Octave-spanning dual frequency comb spectroscopy in the molecular fingerprint region

Spectroscopy in the molecular fingerprint spectral region (6.5-20 $\mu$m) yields critical information on material structure for physical, chemical and biological sciences. Despite decades of effort, this portion of the electromagnetic spectrum remains

We report and characterize low-temperature, plasma-deposited deuterated silicon nitride films for nonlinear integrated photonics. With a peak processing temperature less than 300°C, it is back-end compatible with complementary metal-oxide semiconductor

Dissipative solitons formed in Kerr microresonators offer the promise of chip-scale frequency combs that can extend precision metrology outside of a laboratory environment. We explore the creation of an octave-spanning, 15 GHz repetition rate microcomb
