Title: Indirect optically controlled pseudomorphic HEMT based MMIC oscillator
Issue Date: 1992 Konferenzbeitrag Conference proceedings / 22nd European Microwave Conference 92 : Monday 24th to Thursday 27th August 1992, Helsinki University of Technology, Espoo, Finland. Vol. 1. Tunbridge Wells : Microwave Exhibitions and Publ., 1992. - ISBN 0-946821-82-8, S. 702-706
Abstract: For the first time an indirect optically controlled monolithic integrated oscillator was fabricated and examined experimentally. The oscillator was designed for a frequency of about 7 GHz. By illuminating a 60x60 μm2 photodiode by the light of a pigtailed laser diode (λ=840 nm), the free-running frequency of the oscillator was tunable in a range of more than 7 MHz. A locking range of more than 3 MHz was achieved. A phase shift in the output signal of nearly 180° has been observed.
