Photonic transistors made from metallic photonic quantum wires

We study the absorption and dispersion properties of photonic quantum wires made from a dielectric photonic crystal and a metallic photonic crystal where the former is embedded into the latter. The dielectric crystal is doped with an ensemble of nanoparticles which are interacting with the wire which is acting as a reservoir. The transfer matrix method has been used to calculate the bound states of photons within the wire. A probe and a pump lasers are applied to monitor the absorption and dispersion coefficients. Numerical simulations for localized states, density of states and the absorption coefficients are carried out. It is predicted that system can be switched from two transparent state to the one and vice versa. The present study can be used to make new types of optical devices such as sensors, switches and transistors.
