[Meep-discuss] Multiple wavelengths and light direction

Hi Meep users! I am trying to specify a range of wavelengths between 1.5 and 1.6 to put into my waveguide and I can not find how to do this! Is it possible? Also I only want the light to propagate in the positive y direction, is there a way to do that as well? Thanks!! Lynn

Hi, 1) spectrum: although the gaussian source with frequency around (1/1.55) would give an approximate result, you probably want to use the band_src_time which is described here: http://fzu.cz/~dominecf/misc/meep/index.html#bandsource I am going to contribute the code to github today. 2) If you
