Reply To: Minimize reflection to almost 0%

I have tried to improve my results by decreasing the thickness of the lnP film using the formula t = lambda/(4n) with lambda = 1.5um and n = 3.21 which gives .1168 um. However in the pics I attached the best result I got was at around -.32 on the y axis for 0.12um for y-span. I was told I am supposed to set my source for 1.5 um but I do not know how to do that since I am aiming for mimimum reflection at 1.5 um. Does anyone know of any other equation I can use or how I may alter my lnP film thickness dimensions to get max transmission at 1.5 um if possible? The source is a y axis injection. Thank you in advance!
