Patent ID: 8461620

Claim:
An optically triggered semiconductor switch comprising: a) an anode metallization layer; b) a cathode metallization layer; c) a semiconductor between the anode metallization layer and the cathode metallization layer, comprising at least four layers of alternating doping in a form P-N-P-N, in which an outer layer adjacent to the anode metallization layer forms an anode and an outer layer adjacent the cathode metallization layer forms a cathode; in which the anode metallization layer has a window pattern of optically transparent material exposing the anode layer to light; wherein the window pattern comprises a plurality of windows of transparent material, each window having a top portion with a width, a bottom portion with a width, the top portion being connected to the bottom portion through a middle portion, wherein a width of the middle portion of the window is greater than the width of the top portion and the bottom portion of the window; d) a photon source emitting light having a wavelength, the light emitted from the photon source being configured to match the window pattern of the anode metallization layer.
