Abstract:
A method of forming a photonic crystal on a semiconductor substrate, the substrate having a receiving region, the method comprising the steps of:forming a first layer of material over the substrate, the first layer of material having a first dielectric constant; forming a second layer of material on the first layer of material, the second layer of material having a second dielectric constant; repeating the forming the first layer step and the forming the second layer step a predetermined number of times to form a multi-layered structure with alternating layers, the multi-layered structure having a top layer and a plurality of underlying layers, the top layer having a top surface; etching the top layer and the underlying layers to form a plurality of photonic stacks and a space between the photonic stacks, the plurality of photonic stacks having a plurality of top surfaces; and forming a layer of interstack material over the substrate to fill up the space between the photonic stacks.
