Abstract: | A linear system model for planar concave grating demultiplexer is developed based on the scalar diffraction theory. With this model the system can be simulated by using Fourier transform. Many device performances such as dispersion features, N × N interconnection, channel uniformity, insertion loss, crosstalk can be estimated or optimized. Furthermore, the behavior of aberration is included in the generalized model. |
