EarthFinder: A Precise Radial Velocity Probe Mission Concept For the Detection of Earth-Mass Planets Orbiting Sun-like Stars
Peter Plavchan, Bryson Cale, Patrick Newman +40
EarthFinder is a Probe Mission concept selected for study by NASA for input to the 2020 astronomy decadal survey. This study is currently active and a final white paper report is d…
2.4-THz Bandwidth Optical Coherent Receiver Based on a Photonic Crystal Microcomb
Callum Deakin, Jizhao Zang, Xi Chen +5
We demonstrate a spectrally-sliced single-polarization optical coherent receiver with a record 2.4-THz bandwidth, using a 200-GHz tantalum pentoxide photonic crystal microring reso…
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…
Mid-infrared frequency combs at 10 GHz
Abijith Kowligy, David Carlson, Daniel Hickstein +5
We demonstrate mid-infrared (MIR) frequency combs at 10 GHz repetition rate via intra-pulse difference-frequency generation (DFG) in quasi-phase-matched nonlinear media. Few-cycle…
EarthFinder Probe Mission Concept Study: Characterizing nearby stellar exoplanet systems with Earth-mass analogs for future direct imaging
Peter Plavchan, Gautam Vasisht, Chas Beichman +52
EarthFinder is a NASA Astrophysics Probe mission concept selected for study as input to the 2020 Astrophysics National Academies Decadal Survey. The EarthFinder concept is based on…
Photonic-chip supercontinuum with tailored spectra for precision frequency metrology
David Carlson, Daniel Hickstein, Alexander Lind +11
Supercontinuum generation using chip-integrated photonic waveguides is a powerful approach for spectrally broadening pulsed laser sources with very low pulse energies and compact f…
Thermal and Nonlinear Dissipative-Soliton Dynamics in Kerr Microresonator Frequency Combs
Jordan Stone, Travis Briles, Tara Drake +4
We explore the dynamical response of dissipative Kerr solitons to changes in pump power and detuning and show how thermal and nonlinear processes couple these parameters to the fre…
Dual-microcavity narrow-linewidth Brillouin laser
William Loh, Adam Green, Frederick Baynes +6
Ultralow noise, yet tunable lasers are a revolutionary tool in precision spectroscopy, displacement measurements at the standard quantum limit, and the development of advanced opti…
