Abstract
An integrated optical transmission element may be provided. The integrated optical transmission element includes an optical cavity including an input port and an output port, and photorefractive material within the optical cavity. A transmission of light from the input port to the output port is persistently changeable by an optical control signal provided to the photorefractive material, the optical control signal being configured to change a refractive index.
Claims12
An integrated optical transmission element, the optical transmission element comprising:
- an optical cavity comprising an input port and an output port;
- and
- photorefractive material within the optical cavity,
- wherein transmission of light from the input port to the output port is persistently changeable by an optical control signal provided to the photorefractive material, the optical control signal being introduced to change a refractive index of the photorefractive material, the change in the refractive index persisting indefinitely following reception of the optical control signal.
