Implementation of photonic crystal based all-optical half adder using T-shaped waveguides

All-optical photonic crystal based half adder is proposed using T-shaped waveguides with out of phase inputs. T-shaped waveguides at the input section act as light beam splitters to provide input to the T-shaped waveguides at the output section which acts as power combiners according to the input phase. A separate 180° phase shifter is designed and used at… CONTINUE READING
