Semiconductor device for generating modulated radiation

Claim 1

IN COMBINATION, A SEMICONDUCTOR DEVICE INCLUDING A BODY OF SEMICONDUCTOR MATERIAL WITH A DOT OF MATERIAL ALLOYED INTO ONE SURFACE TO FORM A P-N JUNCTION, SAID DEVICE BEING OF THE TYPE IN WHICH CHARGE CARRIERS RECOMBINE IN TWO COMPETING WAYS AT LEAST ONE OF WHICH IS RADIATIVE, AN ELECTRODE IN OHMIC CONTACT WITH SAID BODY ON SAID ONE SURFACE, A CONDUCTIVE MESH ELECTRODE INSULATED FROM A SECOND SURFACE OF SAID BODY, MEANS CONNECTED BETWEEN SAID FIRST ELECTRODE AND SAID DOT FOR CONTINUOUSLY INJECTING CHARGE CARRIERS INTO SAID DEVICE TO THEREBY CAUSE EMISSION THEREFROM THROUGH SAID MESH ELECTRODE AT A FREQUENCY CHARACTERISTIC OF THE RADIATIVE RECOMBINATION OF THE CHARGE CARRIERS, AND MEANS SEPARATE FROM SAID INJECTION MEANS FOR APPLYING A MODULATING SIGNAL BETWEEN SAID FIRST ELECTRODE AND SAID MESH ELECTRODE FOR MODULATING THE RECOMBINATION PROCESS COMPETING WITH SAID RADIATIVE RECOMBINATION TO THEREBY MODULATE THE EMITTED RADIATION.
