Control óptico de un oscilador MMIC en banda Ku

Abstract

This paper shows the latest results research on the optical control of a GaAs chip monolithic Voltage Controlled Oscillator, and is an extension of previous work realized by our group in the field of opticalmicrowave interaction. The oscillator was originally designed for the transmitter stage of a VSAT communications front-end system in the 14.5 GHz band. The possibilities of optical control of the VCO by illumination of the PHEMT transistor are demonstrated through measurements of the oscillation output power and frequency. An optical control range of 8dB of oscillation output power and up to 400MHz of oscillation frequency has been obtained.
