Abstract

A non-reciprocal optical device mapping a series of optical input/output signal waveguides to a corresponding series of optical input/output signal waveguides, the device comprising: a series of spaced apart input/output waveguides; a reflective imaging system for reflecting and focussing light emitted from the input/output waveguides; a plurality of crystal elements between the input/output waveguides and the reflective imaging means; at least one non-reciprocal polarization rotation element; wherein light emitted from a first input/output waveguide is transmitted to a second input/output waveguide in a polarization independent manner and light emitted from the second input/output waveguide is transmitted away from the first input/output waveguide.
