Abstract

Self-electrooptic effect devices (SEEDs) and GaAs field- effect transistors (FETs) are used to form smart pixels. A 8 X 4 array of simple field-effect transistor-self- electrooptic effect device (FET-SEED) smart pixels has been fabricated by interconnecting a SEED chip and a GaAs FET chip on a printed circuit board. The smart pixel consists of a detector SEED, a modulator SEED, and a simple GaAs FET amplifier. An optical system have been designed and constructed to demonstrate the smart pixels. The operational principle of the smart pixels is also described.
