Abstract
An optical isolator for suppressing back reflections from a downstream optical system is described. The optical isolator includes a plurality of optical paths between a splitter and a combiner. One or more of the optical paths include two phase modulators that are driven by oscillating signals having predefined phase relationships. At least one bypass optical path does not include two phase modulators driven by oscillating signals. Amplitude and phase of an optical signal traversing the bypass optical path may be tuned to further suppress residual reflections from a downstream optical system.
