Claim Text:
1. An optical assembly comprising; a first dissipative optical system; a second optical system coupled in an energy transfer communication with said first optical system, said second optical system configured to receive a flow of energy from an external source, said second optical system configured to transfer at least a portion of the received flow of energy to said first optical system through the energy transfer communication wherein the received flow of energy of said second optical system is approximately equal to a dissipated energy of the first optical system; said first dissipative optical system and said second optical system are configured to operate below or above a transitional coupling strength thereby configured to effect phase transition from operating in a linear unbroken parity-time symmetry operation to a broken parity-time symmetry operation thereby inducing a non-reciprocal energy transmission, where the at least a portion of the received flow of energy transferred to said first optical system from said second optical system is selectable using at least one of an amount of couple between said first optical system and said second optical system and a gain of said second optical system.
