OptiGrating uses the Coupled Mode Theory to model the light and enable analysis and synthesis of gratings.

OptiGrating Overview

 

 

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
