Low crosstalk losses in silicon-on-insulator (SOI) waveguides are demonstrated. The proposed crossing structure has a high compactness, a broad bandwidth with almost flat transmission losses and constant crosstalk losses and is robust against fabrication inaccuracies.
Low crosstalk losses in silicon-on-insulator waveguides are demonstrated by choosing the optimum crossing angle. It is obtained that by using the crossing angles of 60deg or 120deg instead of the conventional 90deg crossing angle crosstalk losses are improved by more than 10 dB without degrading transmission losses. Experimental results show a very good agreement with three-dimensional finite-difference...
Summary form only given. Different techniques have been reported to compensate the distortion effects of polarization mode dispersion (PMD) in long haul optical transmission systems. The system presented here basically uses a liquid crystal optical polarization controller and a polarizer. It features simplicity, ability to compensate a wide range of differential group delays, and also avoids the utilization...
