Optical Frequency Averaging of Light
William Loh, Ryan T. Maxson, Alexander P. Medeiros +3
The use of averaging has long been known to reduce noise in statistically independent systems that exhibit similar levels of stochastic fluctuation. This concept of averaging is ge…
Cooling of an Integrated Brillouin Laser below the Thermal Limit
William Loh, Dave Kharas, Ryan Maxson +5
Photonically integrated resonators are promising as a platform for enabling ultranarrow linewidth lasers in a compact form factor. Owing to their small size, these integrated reson…
Roadmap on Integrated Quantum Photonics
Galan Moody, Volker J. Sorger, Daniel J. Blumenthal +52
Integrated photonics is at the heart of many classical technologies, from optical communications to biosensors, LIDAR, and data center fiber interconnects. There is strong evidence…
A Brillouin Laser Optical Atomic Clock
William Loh, Jules Stuart, David Reens +6
Over the last decade, optical atomic clocks have surpassed their microwave counterparts and now offer the ability to measure time with an increase in precision of two orders of mag…
Integrated multi-wavelength control of an ion qubit
Robert J. Niffenegger, Jules Stuart, Cheryl Sorace-Agaskar +10
Monolithic integration of control technologies for atomic systems is a promising route to the development of quantum computers and portable quantum sensors. Trapped atomic ions for…
Ultra-Narrow Linewidth Brillouin Lasers with Nanokelvin Thermometry
William Loh, Siva Yegnanarayanan, Frederick O'Donnell +1
Ultrastable lasers serve as the backbone for some of the most advanced scientific experiments today and enable the ability to perform atomic spectroscopy and laser interferometry a…
Low-loss integrated photonics for the blue and ultraviolet regime
Gavin N. West, William Loh, Dave Kharas +5
We present a low-loss integrated photonics platform in the visible and near ultraviolet regime. Fully-etched waveguides based on atomic layer deposition (ALD) of aluminum oxide ope…
Method for Determination of Technical Noise Contributions to Ion Motional Heating
J. A. Sedlacek, J. Stuart, W. Loh +4
Microfabricated Paul ion traps show tremendous promise for large-scale quantum information processing. However, motional heating of ions can have a detrimental effect on the fideli…
High-Fidelity, Single-Shot, Quantum-Logic-Assisted Readout in a Mixed-Species Ion Chain
Colin Bruzewicz, Robert McConnell, Jonathon Sedlacek +4
We use a co-trapped ion () to sympathetically cool and measure the quantum state populations of a memory-qubit ion of a different atomic species ($^{40}\mathr…
Microresonator Brillouin Laser Stabilization Using a Microfabricated Rubidium Cell
William Loh, Matthew T. Hummon, Holly F. Leopardi +5
We frequency stabilize the output of a miniature stimulated Brillouin scattering (SBS) laser to rubidium atoms in a microfabricated cell to realize a laser system with frequency st…
A microrod-resonator Brillouin laser with 240 Hz absolute linewidth
William Loh, Joe Becker, Daniel C. Cole +4
We demonstrate an ultralow-noise microrod-resonator based laser that oscillates on the gain supplied by the stimulated Brillouin scattering optical nonlinearity. Microresonator Bri…
Noise and dynamics of stimulated Brillouin scattering microresonator lasers
William Loh, Scott B. Papp, Scott A. Diddams
We use theoretical analysis and numerical simulation to investigate the operation of a laser oscillating from gain supplied by stimulated Brillouin scattering (SBS) in a microreson…
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…
Phase Steps and Hot Resonator Detuning in Microresonator Frequency Combs
Pascal Del'Haye, Aurelien Coillet, William Loh +3
Experiments and theoretical modeling yielded significant progress towards understanding of Kerr-effect induced optical frequency comb generation in microresonators. However, the si…
