Abstract
A new, simple and accurate method to compute the TM reflectivity of multilayer coatings deposited on laser diodes is presented. This is then applied to the optimisation of antireflection coatings. With two-layer coatings it is possible to have near-zero reflectivity for both TE and TM polarisations at some wavelength, and to maintain it below 10-4 over 100 nm
