Hi All, Thanks for MEEP, I have been finding it very useful, and am currently in the process of porting it over to our cluster. Looking forward to it! However, this time I believe I am using MEEP for a possibly inappropriate purpose; I was hoping I could describe the situation and find out whether I can believe the results.
I am attempting to simulate the light propagation of a VCSEL, out of the aperture, through a small air gap, substrate, cladding material, and into a waveguide core. Sparing you the details (unless they are needed), I have modeled this as a 2D structure that would look exactly as a cross-section of this stack up would be drawn. The VCSEL is modeled as a 1-D gaussian source, with the length equal to the aperture diameter. All of these materials are transparent at the wavelength of interest, I am using only a real epsilon for each material. There are several hard index discontinuities. I am getting essentially no propagation through the stack. Is the source a reasonable way to represent the VCSEL? I know the divergence angle of the VCSEL, but don't know how to put collimation into the source. Is this whole situation something that I cannot expect MEEP to help me with?
