Might be scientifically interesting, but all the comments are in Spanish, hence it is very hard to understand and change the code according to ones needs...
I have a quick question on 'fase1'.
I am trying to understand the meaning of "fase1 = exp((i*deltaz*kx.^2)./(nbar*k0 + sqrt(max(0,nbar^2*k0*2 - kx.^2))));" especially max part. I experimentally removed it. but no changes found for graphic result in fact numerical as well.
Can you give some insight on the meaning of the argument and necessity?
@sh.a Provide specific information on what you like and dislike about the submission.
I am new to the field of computational photonics.
Could someone please explain (or refer to some literature of) the terms fase1 and fase2?
@arnold I think a ray-tracing software would be more appropriate in that case.
could you include a spherical and aspherical lens for instance? Would be great.
That's really good! Helped me a lot! The very thing I've been looking for
good, i goona check
can someone expalin to me where the waveguide(core) width and the cladding width are handled in the code for the rectangular waveguide? and what do x0, x1, x2,x3,and x4 stand for?
exelente justo lo que nececitaba
It works very nicely.The m-file of the program can be modified as per the requirement.
Amazing programs, conglatulations is a great contribution, I can not explaind all the possible aplications
