ABSTRACT:
A frequency dependent optical isolator is provided which allows two signals transmitted on a single optical fiber to be isolated in dependence upon their frequencies. A signal having a frequency f1 propagates through the isolator in one direction from a first input/output port to a second input/output port and is prevented from propagating in the reverse direction. A signal having a frequency f2 propagates through the isolator from the second input port to the first input port and is prevented from propagating in the reverse direction. After either of the signals propagates through the isolator from one input/output port to the other, the isolator prevents the respective signal from traveling backwards in a reverse direction through the isolator. The frequency dependent isolator may be used with an amplifier or may amplify one or more of the signals propagating through.
