Logic gates using photonic crystals The implementation of a NOT gate using a photonic crystal is considered first. For this purpose, the optical cavity considered here has a resonance wavelength the same as that of the incident light. This cavity is represented by S in Figure 3. The optical c...
Using the normalization method, the coupled inputs injected into a laser require the same wavelength, while the gain-modulated logic gate requires a multiwavelength input (except for the NOT gate). Thus, a system using the normalization method is assumed to have a common reference with ...
