NON-LINEAR PHOTONIC SWITCH

摘要

A photonic switch (30) may be formed using one of a selected group of non-linear optical materials. Each of the materials within this group has a refractive index that demonstrates a substantial peak as a function of wavelength. The photonic switch (30) includes a positive gain, and thus acts as a photonic transistor. In addition, a photonic switch (30) is formed so that a gate signal is applied in a direction that is substantially perpendicular to the direction of the input signal so that there is no effective contamination of the input signal by the gate signal affecting the output signal.
