Abstract :
This paper describes the experimental results of the optically controlled InP based MMIC oscillator with illumination from the back side of the wafer. The oscillator consists of the InP HEMT and the CPW. The optical frequency shift of the InP MMIC oscillator illuminated from the front side and the back side with 1.5 μm optical source were 28 MHz and 46 MHz around 38 GHz, respectively. It was found that enhancement of the optical tuning with the 1.5 μm laser can be realized by the illumination from the back side of the InP substrate.
