• All optical
• Logic gates
• Non-linear total reflectional switch
• Frequency encoding

A novel method of implementation of frequency encoded logic gates NOT, OR, AND, NOR, NAND, X-OR, X-NOR is discussed. The frequency sources and physical requirements for the implementation are also discussed. The non-linear material (liquid) suitable for these operations to be performed should be of large non-linear coefficient, high reverse saturation absorption, large thermo-optic coefficient and low viscosity. The input controlling beams used to induce non-linearity in the switch are either of frequency v(1) or v(2) and the probe beam is a mixed signal of frequencies v(1) and v(2). Depending on the nature of the controlling inputs the output conditions of the probe can be adjusted to get different logic gates.
