1. An optical system, comprising:

  • a source of electromagnetic radiation;

    a component of said system, capable of optical communication with said source, serving to transmit or reflect at least a portion of the electromagnetic radiation emitted by said source; and

    a device which includes a substantially antireciprocal polarization rotator, said device being capable of optical communication with said source and said component, whereinsaid device exhibits a refractive index profile which includes a first local waveguiding maximum positioned within said rotator, and said device further includes means for reducing the electromagnetic energy of at least a portion of the electromagnetic radiation which traverses said device but is not guided by said rotator during the operation of said system.
