Optical circulator |
摘要 |
<p>An optical circulator having a dual fiber collimator and a single fiber collimator is described. The circulator provides a non-reciprocal functionality that directs input signals from a first fiber of the dual fiber collimator to the single fiber collimator. Input signals from the single fiber collimator are directed to a second fiber of the dual fiber collimator. The circulator includes birefringent wedges that change the angle of signals from the single fiber collimator to direct the signals to the second fiber of the dual fiber collimator. Because the circulator includes two collimators rather than three collimators, the circulator is more compact than a circulator having three collimators. <IMAGE></p> |
