Abstract:
A method of transferring optical signals comprising steps of:receiving a light beam at an input port located on a forward face of an optical assembly,spatially separating said light beam into polarization components within said optical assembly;diverging said polarization components such that a distance between said polarization components progressively increases;redirecting said diverging polarization components to propagate in a substantially parallel manner, including a step of refracting said polarization components using a compensating lens having a plurality of flat surfaces, each of said polarization components being refracted by a particular flat surface of said plurality of flat surfaces;displacing said polarization components in a lateral direction using at least one nonreciprocal optical element;converging said polarization components such that said distance between said polarization components progressively decreases;recombining said polarization components to reform said light beam; andtransmitting said light beam via a predetermined optical line.
