Abstract
A light emitting tunnel diode oscillator comprising a body of single crystalline material having a first portion n-doped and a second portion p-doped in such a way that the resulting p-n junction has the low voltage conductance characteristics of a tunnel diode as well as characteristics of light emission. The light emitting tunnel diode oscillator comprises a plurality of alternately layered n-doped portions and p-doped portions. a light emitting tunnel diode oscillator wherein said first n-doped portion and said second p-doped portion are formed to have a thickness corresponding to an integral number of desired wave lengths.
