ELMSFORD, NY (January 31, 2006) - U.S. Patent No. 6,992,749 , entitled "Scalable and Mass-Manufacturable OXC using Liquid Crystal" issued on January 31, 2006. Congratulations to Dr. Seungug Koh and Sadeg M. Faris. This patent is directed to a 1XN (or NX1) optical connector for steering light, useful in many communications and computing applications. A key advantage of this patent is the integration of components to form a monolithic structure. This patent covers a device that employs a plurality of N stages, each stage including a liquid crystal cell and a polarizing beam splitter. The liquid crystal cell 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 2N outputs. Of course, the direction of light can be reversed, forming an NX1 cell.
