Paper Abstract

One of the main advantages which integrated optoelectronic circuits (IOEC's) have over discrete circuits is the ability to achieve high-frequency modulation due to a significant reduction in parasitic reactances. This is due to the elimination of bond wire connections which have high inductances and to the use of semi-insulating substrates which reduces the parasitic capacitances of bonding pads. While the active electronic devices incorporated in such circuits, e.g., GaAs metal-semiconductor field-effect transistors (MESFET) can be modulated at frequencies exceeding 30 GHz, the overall modulation bandwidth of the integrated optoelectronic circuit is limited, in general,by the frequency response of the light source (i.e., laser) and the photodetector.
