In digital the detection techniques, the half adder is a component of electronic systems that performs calculations faster than the other logic gates.
This article focusses on an all-optical half adder logic gate using a two dimensional T-shaped photonic crystal waveguide and silicon in an air medium.
The half adder design is predicated on the concept of constructive (in-phase) and destructive (out-of-phase) interferences. The high-intensity output
is achieved by carefully selecting the lattice constant, rod radius and refractive index of the half adder structure. The effectiveness of the half adder is
investigated using finite-difference time-domain and plane-wave expansion techniques at 1.55
