1. An optically responsive device comprising:
- a body containing a photo-semiconductor device having an active,light sensitive area;
an optical fiber having first and second ends; and
an index matching material between said first end of said optical fiber and said body so as to optically communicate with the active region thereof, said index matching material being interposed between said optical fiber and said body such as to eliminate air between said optical fiber and said body, the index matching material having an index of refraction matching that of one of said optical fiber and said body.

Abstract
The coupling of optical signals to the active region of a FET having a wide source to drain spacing via an optical fiber and material having an index of refraction matching that of the fiber or the FET so as to increase the locking range when the FET is part of an oscillator circuit or to increase the change in the electrical gain of the FET caused by a change in the optical energy if the FET is an amplifier.
