✦ Synopsis

The impact of particle defects in the free propagation region on the performance of an etched diffraction grating demultiplexer is analyzed in the present paper. Numerical simulations using a method of moment and a Green function method show that particle defects with some special sizes can result in a strong resonance with the incident wavelength and will produce a large scattering loss.

The insertion loss and channel crosstalk of an etched diffraction grating (EDG) demultiplexer is significantly influenced by phase and amplitude errors. A statistical model to estimate the impact of phase and amplitude errors in an EDG is developed using scalar diffraction theory. The numerical resu
