Abstract

Stratified grating couplers (SGCs) designed to couple normally incident light into single mode, low-index contrast waveguides are discussed. SGCs are composed of multiple, shifted, binary grating layers. Preliminary simulations using a micro-genetic algorithm show an in-coupling efficiency of 68%.
