AI Article Synopsis
- A theoretical analysis and experimental demonstration of a depleted optical thyristor (DOT) structure led to the creation of optical logic gates using a vertical cavity laser-depleted optical thyristor (VCL-DOT) for an optically programmable gate array.
- The implementation of optical AND and OR gates was achieved by altering the bias of individual VCL-DOTs, with various optical logic functions executed by modifying the intensity of reference input beams.
- The design focused on enhancing sensitivity and reducing threshold current by balancing a small active region for the laser and a large detecting area through a selective oxidation process.
Article Abstract
We have theoretically analyzed the depleted optical thyristor structure and experimentally demonstrated optical logic gates implemented by monolithically integrated vertical cavity laser--depleted optical thyristor (VCL-DOT) for an optically programmable gate array. The optical AND-and OR-gates have been realized by changing a input bias of the single VCL-DOTs and all kinds of optical logic functions are also implemented by adjusting an intensity of the reference input beams into the differential VCL-DOTs. To achieve the high sensitivity and low threshold current, a small active region of lasing part and a wide detecting area are simultaneously designed by using a selective oxidation process..
