TL;DR: Resonant propagating waves created on the surface of a dielectric multilayer stack, called Bloch surface waves (BSW), can be designed for high sensitivity monitoring of the adjacent refractive index as an alternative platform to the metal-based surface plasmon resonance (SPR) sensing.

TL;DR: Single and multi-layer passive optical interconnects using single mode polymer waveguides are demonstrated using UV nano-imprint lithography and a way to experimentally quantify a small variation in index contrast between core and cladding of fabricated devices is shown.

TL;DR: In this article, a polymer waveguide is fabricated on top of an inverted opal photonic crystal structure to demonstrate an air clad functioning waveguide for the first time to the best of their knowledge.

TL;DR: In this article, the authors present designs for sharp bends in polymer waveguides using colloidal photonic crystal (PhC) structures and simulation results show that core-shell Face Centered Cubic (FCC) colloidal crystals have sufficient refractive index contrast to open up a bandgap in the desired direction when integrated into polymer waveguide and can achieve reflection >70% for the appropriate plane.

TL;DR: In this paper, Khan et al. designed and implemented a micro-structures with refractive index contrast for optical interconnects and sensing applications, which can be used for optical sensor networks.
