TL;DR: An overview of the current state-of-the-art in silicon nanophotonic ring resonators is presented in this paper, where the basic theory of ring resonance is discussed and applied to the peculiarities of submicron silicon photonic wire waveguides: the small dimensions and tight bend radii, sensitivity to perturbations and the boundary conditions of the fabrication processes.

TL;DR: This work proposes a label-free biosensor based on microring cavities in Silicon-on-Insulator (SOI) that fits in an area below 10x10mum(2), and uses the avidin/biotin high affinity couple to demonstrate good repeatability and detection of protein concentrations down to 10ng/ml.

TL;DR: In this paper, the authors compared the performance of photonic wires and photonic-crystal waveguides for photonic integration in silicon-on-insulator (SiOI) circuits.

TL;DR: In this paper, a grating coupler approach was proposed to improve the coupling efficiency of nanophotonic waveguides and a single-mode fiber in photonic circuits.

TL;DR: In this paper, an out-of-plane coupler for butt-coupling from fiber to compact planar waveguides is proposed based on a short second-order grating or photonic crystal, etched in a waveguide with a low-index oxide cladding.
