Beschreibung
Zusammenfassung:	A method comprises: receiving a first optical signal and a second optical signal; injecting a portion of the first optical signal into an optical resonator; injecting a portion of the second optical signal into the optical resonator, where the first optical signal and the second optical signal propagate in opposite directions in the optical resonator; emitting a portion of the first optical signal; emitting a portion of the second optical signal; coupling, by free space optics, a portion of the emitted first optical signal to a first power detector; coupling, by free space optics, a portion of the emitted second optical signal to a second power detector; adjusting the power level of the received first optical signal based upon a first detected power level detected by the first power detector; and adjusting the power level of the received second optical signal based upon a second detected power level detected by the second power detector.
