چکیده
In order to improve mixed optical-electrical microwave devices design, a novel modeling of opto-electronic phenomena as photoconduction effect has been achieved. Multiples photo-induced carriers generations/recombinations processes playing a part in semiconductor subtrates under laser illumination are taken into account and modeled by an equivalent electrical circuit. Various types of modulation applied on the optical signal, laser beam dimensions and intrinsic substrate material characteristics are integrated in order to define GaAs optically-controled switch application device properties. Optical effects on a RF signal propagation feeding microstrip circuit are reachable in both time and frequency domains through the Fourier transforms.

High-speed optical switching based on diffusive conduction in an optical waveguide with surface-normal optical control
We report a surface-normal optically controlled waveguide switch made of a p-i-n diode that utilizes optically induced voltage screening to turn on and diffusive conduction to turn off. We examine theoretically diffusive conduction in these switches and show that this mechanism offers the possibility of creating optical switches operating at several tens of GHz. As a proof-of-concept demonstrat...
متن کاملPhotoconductive-Sampling Time-Interleaved CMOS ADC
High speed analog-to-digital converters capable of digitizing signals with bandwidths of several tens of GHz have applications in high-speed instrumentation, wideband radar and optical communications. However, the design of converters with such high input bandwidths is constrained by the need for wideband sample-and-hold circuits with sufficiently low clock jitter. A number of photonic sampling...

Ultra High-Speed Radio Frequency Switch Based on Photonics
Microwave switches, or Radio Frequency (RF) switches have been intensively used in microwave systems for signal routing. Compared with the fast development of microwave and wireless systems, RF switches have been underdeveloped particularly in terms of switching speed and operating bandwidth. In this paper, we propose a photonics based RF switch that is capable of switching at tens of picosecon...
متن کاملResonant microwave cavity for 8.5-12 GHz optically detected electron spin resonance with simultaneous nuclear magnetic resonance.
We present a newly developed microwave resonant cavity for use in optically detected magnetic resonance (ODMR) experiments. The cylindrical quasi-TE(011) mode cavity is designed to fit in a 1 in. magnet bore to allow the sample to be optically accessed and to have an adjustable resonant frequency between 8.5 and 12 GHz. The cavity uses cylinders of high dielectric material, so-called "dielectri...
