By bridging the dimensional gap between fiber mode and Silicon On Insulator (SOI) layer thickness, 1D and 2D-Grating couplers (GCs) represent promising solutions to the challenge of coupling light into silicon photonics circuits. Considerable work has been done over the last decade towards optimization 1D-GCs, that nevertheless exhibit a very strong sensitivity to the input polarisation state of the fiber, which makes them unsuitable for many inter-system coupling applications. Recently, a new strategy based on a full 3D-FDTD (finite difference time domain) calculations has been proposed to describe 2D-GC operation, and optimize their performance.

The coupling efficiency of a surface grating coupler is optimized for a an arbitrary buried oxide thickness by adjusting the grating radiation angle. The coupler is apodized using a subwavelength structure, allowing a single etch step fabrication. The measured coupling loss is -2.16dB with 3dB bandwidth of 64nm, for a minimum feature size of 100nm. It is also shown by simulations that by implementing this coupler in a double SOI (DSOI) wafer, an ultra-low coupling loss of -0.42dB is achieved.

We demonstrate the synthesis of any arbitrary polarization state of light, spanning the full Poincare sphere, radiated by a single silicon nanoantenna with two feeding waveguides. We experimentally demonstrate the synthesis of linearly, circularly and elliptically polarized light using this method. The reciprocal scenario allows the analysis of light impinging in the nanoantenna, sorting different linear incoming polarization components into different waveguides. Although the method is universal and can be extended to any wavelength and technology, we perform our demonstrations in a CMOS compatible silicon photonics platform, potentially allowing the fast electrical modulation of the amplitude and phase of conventional silicon waveguides to achieve a tuneable polarization synthesizer/analyser.
