FAST ELECTRONIC DRIVER FOR OPTICAL SWITCHES Electronically controlled optical switches are critical components in many optical systems, including pulsed lasers. Solid-state optical switches based upon the Pockels effect are widely utilized in research and industry, however Pockels cells require electronic drivers capable of switching several kilovolts quickly and cleanly. This thesis reviews Po...

This paper introduces an optical AC voltage sensor based on the transverse Pockels effect. The sensor utilizes a bulk Bi(4)Ge(3)O(12) (BGO) crystal as the sensing element. The measurement principle has been described and prototype of the sensor has been constructed and evaluated. Good linearity and accuracy performance was obtained for AC voltage measurement. The proposed sensor can be thus app...

Analysis shows that 400 GbE links using DSP-enabled 5×80Gb/s PAM-4, 4×100Gb/s hybrid CAP-16/QAM-16 and 4×100Gb/s QAM-16-OFDM have relative complexities of 1:5.4:5.7 and consume power of 0.71, 0.67 and 0.75 times that of 16×25Gb/s NRZ benchmark links.

The purpose of this note is to introduce the linear electro-optic effect (Pockels effect) and its applications for modulating the properties of a light wave, such as its phase, polarisation and intensity. For this purpose, basic electromagnetic theory is first reviewed. Some elements of light propagation in an anisotropic medium are then introduced. The linear electro-optic effect is then prese...

A new approach to perform measurement of potentials in high voltage levels using electrooptical Pockels sensors is presented here. This paper describes an application of the White Light Interferometry technique to a high voltage optical fiber measurement system. In this system the information is encoded in the spectrum of the light, allowing the measurement to be independent of the optical powe...

The law of angular momentum conservation is naturally linked to the rotational symmetry of the involved system. Here we demonstrate theoretically how to break the rotational symmetry of a uniaxial crystal via the electro-optic Pockels effect. By numerical method based on asymptotic expansion, we discover the 3D structure of polarization singularities in terms of C lines and L surfaces embedded ...
