Experimental demonstration of an ultracompact polarization beam splitter based on a bidirectional grating coupler
2009 (English)In: Proceedings of SPIE - The International Society for Optical Engineering, 2009, Vol. 7631, 763103- p.Conference paper (Refereed)
A bidirectional grating serving both, as a polarization beam splitter and a vertical coupler for Silicon on Insulator nanophotonic circuits is fabricated and characterized. The measured coupling efficiency is as high as 43%. The demonstrated device has a large 3-dB bandwidth and a high extinction ratio between two orthogonal polarizations.
