Dear Sir
Thank you so much for clearing my doubt on output efficinecy. My aim is to optimize the design of 2D Photonic Crystal based Power splitter in terms of output efficiency. I am injecting the input power at 1550 nm and have introduced certain defects in the crystal structure to get maximum efficiency. Refractive index of the substrate is 3.47 and air holes are injected in it with a refractive index of 1. the size of the splitter is 10×10 micrometer.the air hole radius is 0.2 and radius of defects is 0.1.
The problem is that I am not getting teh desired efficiency at 1550nm. I wanted to know where I am lagging.
