Microring resonator based binary optical full adder

The invention discloses a microring resonator based binary optical full adder which comprises three microring resonators of different structures and five Y-shaped branch-line couplers, is input with three electrical pulse sequences to be calculated and outputs optical pulse sequences after calculation with an addition with a carry flag. The binary optical full adder is completely compatible with aCMOS technology, so that the microring resonator based binary optical full adder is small in size, low in power consumption, rapid in speed, good in extensibility and convenient in integration and play an important role in a photon computer. 本发明公开种基于微环谐振器的二进制光学全加器，由3个不同结构的微环谐振器和5个Y形分支耦合器构成，它有三个待计算的电脉冲序列输入，输出是经过有进位标志的加法计算后的光脉冲序列。本发明二进制光学全加器与CMOS工艺完全兼容，使得器件体积小，功耗低，速度快，可扩展性好，便于集成，在光子计算机中将发挥重要作用。
