ABSTRACT:
A 1XN (or NX1) optical connector for steering light is provided, which may be formed into an optical cross connecter. The optical connector generally includes a plurality of N stages, each stage including a liquid crystal cell and a polarizing beam splitter. The liquid crystal cell, in certain embodiments in the form of an array of LC cells, has a first state for transmitting a first polarization component of the light and a second state for transmitting a second polarization component of the light. The polarizing beam splitter structure reflects one of the polarization states and transmits the other polarization state into one of 2Noutputs. Of course, the direction of light can be reversed, forming an NX1 cell. A key advantage of the present invention is the integration of components to form a monolithic structure.
