Abstract

In accordance with an exemplary embodiment of the present invention, an optical device includes a first element which decomposes said optical signal into a first beam and a second beam with the first beam being in a first polarization state and the second beam being in a second polarization state. The first and second polarization states being orthogonal to one another and including each of said multiple channels. The optical device further includes a second element which transforms the first beam into a first elliptically polarized state having odd channels in a third polarization state and even channels in a fourth polarization state having even channels in the third polarization state and odd channels in the fourth polarization state; and a third element which combines the odd channels into a first output port and the even channels into a second output port.
