Abstract

We show a PT-symmetric coupler having an arm with a tunable gain and a no-loss arm when appropriately de signed to possess reciprocal behavior, unlike its rivals having a fixed gain/loss arm, can perform as a tunable 2 × 2 spatial optical switch. The degree of the tunability equals the ratio of the coupler’s length to the total coupling length.
