Abstract:

Some aspects of the theory of free-carrier-induced refractive index changes in semiconductors are covered as well as some device structures aimed at exploiting this effect to provide for high frequency analog optical modulation are covered in this report. High optical loss and the requirement of large current changes at high frequencies prevented exploiting this effect initially at 10 GHz and then at greater than 30 GHz in the directional coupler architecture. A thermal switch was incidentally explored which had a risetime of 0.3 microseconds and required 0.8 watts to operate.
