A multimode interference (MMI) polarization splitter with easy fabrication process was demonstrated in Silicon-On-Insulator substrate. The minimum device size, 8 µm×1034 µm was designed by Quasi-state imaging effect theory. Numerical simulations show that this optimized MMI polarization splitter has a good fabrication tolerance. The tolerance of width and length is ±0.04 µm and ± 10 µm for transverse...
In this work, we investigate the design of scalar quantizers for the Wyner-Ziv problem, where the decoder has access to a noisy copy of the source. Necessary conditions are given for the design of optimum quantizers with a fixed number of partitions for a criterion consisting of a linear combination of distortion and rate. A simple iterative algorithm is developed to tackle the new quantizer design...
