Deskripsi
A complex grating is approximated by a sequence of uniform segments, and analyzed by connecting the segments with the well-known Transfer Matrix Method. This gives the designer the information needed to test and optimize grating designs. Applications: WDM add/drop, narrow and broadband fiber and waveguide filters; Fiber Bragg reflectors; EDFA gain flattening elements; Dispersion compensators for fiber communications; Sideband suppression using grating apodization; Fiber and waveguide sensors; Long Period Gratings with coupling to cladding modes.
