Abstract
Tera Hertz Optical asymmetric Demultiplexer or TOAD is an important optical switch in optical computational and communication applications. It is used to design different types of logic gates and logic circuits. In this chapter, we have utilized it to design a frequency-encoded optical XOR gate, half adder, and half subtractor using TOAD-based switch for the first time. The input/output bit patterns along with ON/OFF ratio is also investigated.
