Parametric seeding of a microresonator optical frequency comb

July 16, 2013
Author(s)
Scott B. Papp, Pascal P. Del'Haye, Scott A. Diddams
We have investigated parametric seeding of a microresonator frequency comb (microcomb) by way of a pump laser with two intensity modulation sidebands. We show that the pump-sideband spacing is precisely replicated throughout the microcomb's optical

Mechanical Control of a Microrod-Resonator Optical Frequency Comb

July 8, 2013
Author(s)
Scott B. Papp, Pascal P. Del'Haye, Scott A. Diddams
Robust control and stabilization of optical frequency combs enables an extraordinary range of scientific and technological applications, including frequency metrology at extreme levels of precision, novel spectroscopy of quantum gases and of molecules from

Laser-Machined Ultra-High-Q Microrod Resonators for Nonlinear Optics

June 7, 2013
Author(s)
Pascal P. Del'Haye, Scott B. Papp, Scott A. Diddams
Optical whispering-gallery microresonators are useful tools in microphotonics, and non-linear optics at very low threshold powers. Here, we present details about the fabrication of ultra-high-Q whispering-gallery-mode (WGM) resonators made by CO2-laser

Hybrid Electro-Optically Modulated Microcombs

December 28, 2012
Author(s)
Pascal P. Del'Haye, Scott B. Papp, Scott A. Diddams
Optical frequency combs based on mode-locked lasers have proven to be invaluable tools for a wide range of applications in precision spectroscopy and metrology. Recently, a novel principle of optical frequency comb generation in whispering gallery mode

Mechanical stabilization of a microrod-resonator optical frequency

May 24, 2012
Author(s)
Scott B. Papp, Pascal P. Del'Haye, Scott A. Diddams
We present line-spacing frequency control of a microresonator-based optical frequency comb by way of mechanical actuation. Using this novel technique we have achieved a record level of residual stability in the line spacing of 5 × 10 -15 for 1s averaging

Sub-micron force detection using optically-cooled levitated microspheres

September 3, 2010
Author(s)
Andrew Geraci, Scott B. Papp, John E. Kitching
We propose an experiment using optically trapped and cooled dielectric microspheres for the detection of short-range forces. The center-of-mass motion of a microsphere trapped in vacuum can experience extremely low dissipation and quality factors of 10 12
