Modulation of unpolarized light

System and method for effectuating substantially uniform modulation of unpolarized light. Unpolarized light is split into two beams, each beam comprising a different orthogonal mode. The mode of one beam is changed and then the beam is modulated. The other beam is modulated and then its mode is chan...

Zusammenfassung:	System and method for effectuating substantially uniform modulation of unpolarized light. Unpolarized light is split into two beams, each beam comprising a different orthogonal mode. The mode of one beam is changed and then the beam is modulated. The other beam is modulated and then its mode is changed. The two modulated beams are combined to form a modulated multi-mode signal.
