A novel fault-tolerant architecture is introduced in this SBIR program for optical signal processing applications. This structure is based on three key features: 1) polarization manipulation; 2) complementary polarization design and 3) design of throwaway undesired optical energies. The polarization manipulation provides the basis for "no-moving" parts optical switching. The complementary polarization design provides a high polarization extinction-ratio conversion using liquid crystal switching elements. Finally, the throwaway concept achieves high-prefromance, low crosstalk optical signal processing units that are independent of the operating environments and conditions. Proof-of-principle 1 x 2 optical switches have been constructed in Phase I of the study. This switch has a specification of
