SU-8 Polymer as an Optical Waveguide for Integrated Optics
Abstract: Abstract: Optical integrated circuits analogous to electronic integration have many advantages over the latter technology. As information carriers are photons (bosons) in optical circuits rather than electrons (fermions), which maximize the speed as well as due to minimum mutual interaction between photons, losses are reduced whereas the band-width increases. Silicon is most dominant material in fabrication of Electronic Integrated Circits (EICs), Photonic Integrated Circuits (PICs) exploits the suitable optical properties …
