Abstract

An electro-optical transistor chopper (see Division G1) comprises a light-emitting semi-conductor diode optically coupled to a transistor or transistors. The diode comprises a hemispherical region of N-type conductivity 92 and a P-type region 94. When forward biased, the rectifying junction 96 between the regions emits light which passes through the antireflection coating 108 and is reflected by the gold mirror 104 on to a transistor having two emitters 84, 86 diffused into a base region 82 which is itself diffused into a collector substrate 80. The transistor and the diode are stuck together by a pliable transparent cement 102. To avoid absorption of radiation in the hemisphere, it is composed of material having a larger band gap than the material in which the junction 96 is located. Ga As0. 6 is preferred for the region in which the junction is located and Ga Asx P1-x, where x \s5 0.5 for the hemisphere. Indium-gallium arsenide may be used. Either the junction is diffused into the hemisphere which is subsequently etched to produce the region 94, or the region 94 is produced epitaxially. The transistor is composed of germanium or silicon. In modifications the double emitter transistor is replaced by two transistors connected in parallel, Fig. 14 (not shown), or with commonly connected collectors and bases, Fig. 9 (not shown). In these embodiments the transistors are formed on a glass substrate. In another modification, Fig. 10 (not shown), the N-type region of the light-emitting diode is of planar form.
