CW LASER Control of MMICs

The results of our research on the electro-optical control of MMICs are shown in this paper. Two different devices have been investigated: a GaAs chip monolithic amplifier at S band, and an AlGaAs chip MMIC voltage controlled oscillator at Ku. The possibilities of optical control of the amplifier are evidenced as follows: if the amplifier operates with the same biasing, the gain can be opticall...

Computer controlled cw laser spectrometer.

A computer controlled cw UV-visible dye laser source for spectroscopic use has been developed. Computer control facilitates both continuous single-frequency scanning and data acquisition. With 4 W of Ar-ion laser pump power, such a spectrometer can generate in excess of 1 W of cw single-frequency power in the visible and up to 1 mW in the UV by using extracavity nonlinear optical mixing. The la...

GaAs MESFET Photoresponse to CW Laser Probe

An effect, in planar GaAs MESFETs, whereby a sharp increaSe in optical gain at the transistor edges occurs, is reported. This gain effect only manifests when a large resistor is inserted in ser-ies with the gate, to produce the conditions for photovoltaic gate biasing. The mechanism for increased gãin, at t'he edges, is suggested to be due to carrier photogeneration in the substrate that is sub...
