Interferometric Fiber Optic Sensors
Sensors, 2012 Fiber optic interferometers to sense various physical parameters including temperature, strain, pressure, and refractive index have been widely investigated. They can be categorized into four types: Fabry-Perot, Mach-Zehnder, Michelson, and Sagnac.

The many facets of the Fabry-Perot [PDF]
, 2016 We address the response, both in amplitude and intensity, of a Fabry-Perot from a variety of viewpoints. These complementary pictures conspire to achieve a comprehensive and consistent theory of the operation of this system.Comment: 15 pages, 9 ...

Do Eclipse‐Induced Thermospheric TADs Originate From Above or Below?
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Solar eclipses generate significant wave activity in the Earth's upper atmosphere. The source region of eclipse‐induced Traveling Atmospheric Disturbances (TADs) in the upper thermosphere—particularly the relative contributions of gravity waves from the thermosphere itself versus the lower atmosphere—remains unknown. Using the Whole Atmosphere

Diffractively coupled Fabry-Perot resonator with power-recycling
, 2011 We demonstrate the optical coupling of two cavities without light transmission through a substrate. Compared to a conventional coupling component, that is a partially transmissive mirror, an all-reflective coupler avoids light absorption in the substrate

A squeezed state source using radiation pressure induced rigidity [PDF]
, 2005 We propose an experiment to extract ponderomotive squeezing from an interferometer with high circulating power and low mass mirrors. In this interferometer, optical resonances of the arm cavities are detuned from the laser frequency, creating a ...

Cascading of Liquid Crystal Elastomer Photomechanical Optical Devices
, 2010 Photomechanical actuation is demonstrated in two coupled liquid crystal elastomer photomechanical optical devices (PODs) acting in series. The response function of an individual POD is characterized and used to predict the temporal response of the ...

Field Programmable Gate Array‐Based Control Systems for Highly Stable Laser Applications
Advanced Photonics Research, Volume 7, Issue 4, April 2026.This review highlights the transition from analog to FPGA‐based digital architectures for laser frequency stabilization, noting their superior latency and flexibility. It focuses on Modulation Transfer Spectroscopy (MTS) as a robust, background‐free method for high‐precision locking that minimizes residual amplitude modulation.
