Classification: CPC G | IPC G

Claim 0:
1. A solid-state electro-optic device with an electrically variable aperture, comprising:
at least one superlattice semiconductor device including an alternating stack of first semiconductor layers having a first dopant and second semiconductor layers having a second dopant;
wherein the alternating stack of the first semiconductor layers includes a patterned portion defining a first transparent transitioning region between a first pair of electrical connectors, and a second transparent transitioning region between a second pair of electrical connectors;
wherein the first and second pairs of electrical connectors are configured to receive a first voltage to induce a first optical state of the first and second transparent transitioning regions such that a first amount of light is transmitted through the alternating stack; and
wherein the first and second pairs of electrical connectors are configured to receive a second voltage to induce a second optical state to the first transparent transitioning region, while maintaining the first state of the second transparent transitioning region such that a second amount of light different from the first amount is transmitted through the alternating stack.
