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.Abstract:
We have designed and fabricated an out-of-plane coupler for butt-coupling from fiber to compact planar waveguides. The coupler is based on a short second-order grating or photonic crystal, etched in a waveguide with a low-index oxide cladding. The coupler is optimized using mode expansion-based simulations. Simulations using a 2-D model show that up to 74% coupling efficiency between single-mode fiber and a 240-nm-thick GaAs-AlO/sub x/ waveguide is possible. We have measured 19% coupling efficiency on test structures.read more

TL;DR: In this paper, the authors provide an overview of the state of the art in silicon photonics and outline challenges that must be overcome before large-scale commercialization can occur, in particular, for realization of integration with CMOS very large scale integration (VLSI) and must operate within thermal constraints of VLSI chips.

Waveguiding in Planar Photonic Crystals
TL;DR: In this paper, a two-dimensional confinement by photonic crystals in the plane of propagation, and total internal reflection to achieve confinement in the third dimension were demonstrated. But they were not shown to guide light at 1550 nm around sharp corners where the radius of curvature is similar to the wavelength of light.
