Hi Raja,
In addition to this i would like to share applications of OptiBPM.
They are as:
Mature AWG design environment
Large scale optical circuit design capabilities
Waveguides from a diffused process
Model non-symmetrical waveguide structures
Channel, rib or ridge waveguide design
Buried waveguides
Sensor structures
Design optical splitters, combiners, couplers, multiplexers, and modulators.
The width of a waveguide (constant or variable) is defined as perpendicular to the path along the waveguide center.
Thanks and regards,
Rajguru
