Abstract
A method and system for optical systems based on parity-time symmetry and its breaking, and for nonreciprocal light transmission in a parity-time symmetric micro-resonator system are provided. The system includes an optical assembly that includes a first dissipative optical system and a second optical system coupled in energy transfer communication with the first optical system. The second optical system is configured to receive a continuous flow of energy from an external source and to transfer energy to the first optical system through the couple wherein the energy transferred to the first optical system from the second optical system is approximately equal to the energy dissipated in the first optical system, where the energy transferred to the first optical system from the second optical system is selectable using at least one of an amount of couple between the first optical system and the second optical system and a gain of the second optical system.
