A Large Area Fiber Optic Gyroscope on multiplexed fiber network [PDF]

open access: yes, 2013
We describe a fiber optical gyroscope based on the Sagnac effect realized on a multiplexed telecom fiber network. Our loop encloses an area of 20 km2 and coexists with Internet data traffic.

An Optical Apparatus for Rotation and Trapping [PDF]

open access: yes, 2010
We present details of the design, construction, and testing of a single-beam optical tweezers apparatus capable of measuring and exerting torque, as well as force, on microfabricated, optically anisotropic particles (an "optical torque wrench"). The control of angular orientation is achieved by rotating the linear polarization of a trapping laser with ...

Polarization resolved four-wave-mixing-based measurement in bulk material semiconductor optical amplifier [PDF]

open access: yes, 2006
The anticipated growth in demand for bandwidth leads to the development of all-optical signal processing techniques at ever increasing data rates. One possible candidate to achieve the required performance is the semiconductor optical amplifier (SOA). It

Fluctuation-mediated orbital rotation of microparticles in non-coaxially counter-propagating optical tweezers [PDF]

open access: yes, 2023
We have demonstrated in the present report that dielectric microparticles exhibited orbital rotation in the light field of non-coaxially configured two counter-propagating laser beams both in numerical simulations and experiments.

Alignment Method of an Axis Based on Camera Calibration in a Rotating Optical Measurement System

open access: yesApplied Sciences, 2020
The alignment problem of a rotating optical measurement system composed of a charge-coupled device (CCD) camera and a turntable is discussed. The motion trajectory model of the optical center (or projection center in the computer vision) of a camera ...

Using a GPS-Aided Inertial System for Coarse-Pointing of Free-Space Optical Communication Terminals [PDF]

open access: yes, 2006
In the Capanina project, it has been shown that it is possible to use solely GPS positions for coarse-pointing of a stratospheric free-space optical communication terminal.

Optical rotation quasi-phase-matching for circularly polarized high harmonic generation. [PDF]

open access: yesOptics Letters, 2012
A scheme for quasi-phase-matching high harmonic generation of circularly polarized radiation is proposed: optical rotation quasi-phase-matching (ORQPM).

Nanoscale rotational optical manipulation

open access: yesOptics Express, 2020
Light has momentum, and hence, it can move small particles. The optical tweezer, invented by Ashkin et al. [Opt. Lett. 11, 288 (1986)] is a representative application. It traps and manipulates microparticles and has led to great successes in the biosciences.
