Photonic Systems Engineering: a Structured Approach to Positioning, Navigation and Timing Using Microresonators (JTu1I.1)
Presenter: Ying Lia Li, UCL

Optical microresonator gyroscopes, accelerometers and frequency combs are ideally suited for positioning, navigation and timing (PNT) applications. Using the example of a microresonator accelerometer, I present a systems engineering approach to PNT commercialisation.

A Chip-Based Brillouin Laser Gyroscope With Earth-Rotaton-Rate Sensitivity (JTu1I.2)
Presenter: Kerry Vahala, California Institute of Technology

The physical principles of a chip-based Brillouin laser gyroscope are reviewed. The device can resolve sinusoidal rotations with amplitude as low as 5 degrees/hour and is also used to detect the Earth’s rotation.

Integrated Ultra-Narrow Linewidth Ultra-Stable Brillouin Lasers and Their Application to PNT Applications (JTu1I.3)
Presenter: Daniel Blumenthal, University of California Santa Barbara

We describe a new class of photonic integrated ultra-narrow linewidth, ultra-stable Brillouin laser that enables precision spectrally-pure lasers at the chip-scale and their use in atomic clocks, quantum sensing, and optical gyros.

Integrated Optomechanical Sensing for Semiconductor Metrology (JTu1I.4)
Presenter: Andrea Fiore, Eindhoven University of Technology

In this talk we will present recent process on the integration of nano-opto-electro-mechanical sensors with photonic circuits and optical read-out, showing a route towards fully-integrated optical sensing

Chip-Scale Optomechanics for Precision Navigation (JTu1I.5)
Presenter: Jaime G. Flor Flores, UCLA

Laser-driven optomechanical transduction has enabled precision measurements at the thermodynamical limits. Here we present measurements of laser-driven silicon optomechanical oscillators in force-acceleration sensing at mg/Hz1/2-levels for inertial navigation, supported by our theory and device nanofabrication.

We'll be uploading the recorded video by this evening. If the recorded video upload window is not available, we'll send you a link to the recording -- if you can help upload into the CLEO server, it would make the session run more smoothly. Thank you for the patience and look forward,

Miniature High Performance Gyroscopes With Crystalline WGM Resonators (JTu1I.6)
Presenter: Lute Maleki, OEwaves, Inc.

Several groups around the word have been striving to achieve performance similar to fiber gyros and laser gyros in miniature form factors. At OEwaves we have demonstrated that ultra-high quality factor and exceptional transparency of whispering gallery mode resonators fabricated with crystalline material can be put to advantage to realize miniaturehigh performance gyros.
