Claim 17:
18. A method, comprising:
coupling a first polarization selective reflector to a second polarization selective reflector so that a first plane defined by the first polarization selective reflector intersects, at a first angle, a second plane defined by the second polarization selective reflector so that the first polarization selective reflector is configured to direct first light having a first polarization toward the second polarization selective reflector and the second polarization selective reflector is configured to direct second light having a second polarization toward the first polarization selective reflector, wherein the first angle is an acute angle, and the first angle is measured between a portion of the first plane that directs the first light and a portion of the second plane that directs the second light.
