Asynchronous, self-controlled, all-optical label and payload separator using nonlinear polarization rotation in a semiconductor optical amplifier [PDF]

, 2004
We demonstrate an all-optical label and payload separator based on nonlinear polarization rotation in a semiconductor optical amplifier (SOA). The proposed scheme uses a packet format composed of a label and payload information signal combined with a ...

A sensitivity-enhanced optical heterodyne polarimeter for the measurement of optical rotation angle of chiral media [PDF]

, 2011
[[abstract]]A novel heterodyne polarimeter is designed to measure the concentration of chiral media. Optical common-path for the interference of the TE and TM waves, after a polarizer, is set up in our system to reduce noises from the environment.

Synthesis and Conformation of Substituted Chiral Binaphthyl-Azobenzene Cyclic Dyads with Chiroptical Switching Capabilities

Molecules, 2011
Optically active binaphthyl-azobenezene cyclic dyads were synthesized to develop a photochromic switching molecule. Azobenezene moieties were cis-trans isomerized by photoirradiation.

Deep learning-based method for analyzing the optically trapped sperm rotation

Scientific Reports, 2023
Optical tweezers exert a strong trapping force on cells, making it crucial to analyze the movement of trapped cells. The rotation of cells plays a significant role in their swimming patterns, such as in sperm cells. We proposed a fast deep-learning-based

Experimental analysis of four-wave mixing in a semiconductor optical amplifier using frequency resolved optical gating [PDF]

, 2007
Four-wave mixing was performed in a multi-quantum well semiconductor optical amplifier in order to demultiplex 2 ps pulses from 80 GHz to 10 GHz. The demultiplexed pulses were measured using frequency resolved optical gating.

Square pulse emission with ultra-low repetition rate utilising non-linear polarisation rotation technique

The Journal of Engineering, 2014
The generation of nanosecond square pulse and microsecond harmonic pulse in a passively mode-locked fibre ring laser is demonstrated by inserting a 20 km long single mode fibre in the cavity. The laser operates in anomalous region based on the non-linear
