Hi Scott
Thanks a lot for your response.
I have seen all the suggestions and will work upon it. Further, I have some doubts as follows-
1. Regarding the relation between injected field and waveguide dimensions.
2. How to adjust the mesh size (resolution) in relation to the source wavelength.
3. What changes in the waveguide parameters I need to do to get the result beyond 1.4um (else suggest the relation between them).
I will be very thankful to you as this will be really helpful in my research.
Hoping for a favorable reply.
