Fast switchable electro-optic radial polarization retarder

Fast switchable electro-optic radial polarization retarder.

A fast and switchable electro-optic radial polarization retarder (EO-RPR) fabricated using the electro-optic ceramic Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3) is presented. This EO-RPR is useful for fast and switchable generation of a pure cylindrical vector beam. When used together with a pair of half-wave plates, the EO-RPR can change circularly polarized light into any cylindrical vector beam of inter...

Tunable electro-optic polarization modulator for quantum key distribution applications

A tunable polarization retarder based on a bulk buried heterostructure semiconductor waveguide has been demonstrated for the specific application of quantum key distribution. Simplicity of construction, low drive voltage, wide spectral range of operation and potentially high frequency response make it ideal for polarization modulation at the transmitter (Alice) and receiver (Bob) in at least tw...

An Electro-Optic Deflector for a Fast Laser-Wire Scanner

A large aperture electro-optic deflector has been designed, realized and tested for application on a laser-wire-scanner for particle accelerators. Results on the important parameters such as deflection strength, speed and mode quality preservation are shown and discussed. This report was presented in the EPAC Conference under the reference TUPC123 [email protected] !"#$%$&'()*)+',&#-$.%$...

Slow-fast dynamics of a time-delayed electro-optic oscillator.

Square-wave oscillations exhibiting different plateau lengths have been observed experimentally by investigating an electro-optic oscillator. In a previous study, we analysed the model delay differential equations and determined an asymptotic approximation of the two plateaus. In this paper, we concentrate on the fast transition layers between plateaus and show how they contribute to the total ...
