Low Loss Nanostructured Polymers for Chip-scale Waveguide Amplifiers

Abstract On-chip waveguide amplifiers offer higher gain in small device sizes and better integration with photonic devices than the commonly available fiber amplifiers. However, on-chip amplifiers have yet to make its way into the mainstream due to the limited availability of materials with ideal li...
