Fully integrated optical polarimeter

A simple optical electron polarimeter

It is pointed out that heavy atoms (i.e. those which have spectroscopically resolvable fine structure) are not required for optical measurements of electron polarisation. A polarimeter which uses helium gas instead of heavy-metal vapour is proposed, and several experimental details are discussed. Optical detection of electron polarisation was first proposed more than a decade ago by Farago and ...

A Sensitivity-Enhanced Optical Heterodyne Polarimeter for the Measurement of Optical Rotation Angle of Chiral Media

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. A phase-variable waveplate is placed behind the sample to enhance the phase signal change of rotation of polarization introduced by the sample itself. This enhan...

Fabrication of fully integrated antiresonant reflecting optical waveguides using the femtosecond laser direct-write technique.

Utilizing a recently developed two-step fabrication process, we have experimentally demonstrated what is to the best of our knowledge the first ever integrated antiresonant reflecting optical waveguide (ARROW), directly inscribed into bulk optical glass. The waveguide consists of an array of high-index contrast rods that surround an unmodified core. The transmission spectrum reveals the formati...

Fully integrated serial-link receiver with optical interface for long-haul display interconnects

We report a fully integrated serial-link receiver with optical interface fabricated with a 0.18 mm complementary metal oxide semiconductor technology for long-haul display interconnects. The receiver includes a trans-impedance amplifier, a limiting amplifier, a clock and data recovery circuit, 1:64 de-multiplexer and a built-in error checker. The receiver produces 64-bit wide electrical signals...
