TL;DR: A highly efficient grating structure for the coupling between standard optical fibers and single-mode waveguides in the silicon-on-insulator platform realized in a CMOS fabrication process is presented.
Journal ArticleDOI
CMOS-Compatible Polarization Splitting Grating Couplers With a Backside Metal Mirror
TL;DR: In this paper, a 1-D grating structure that serves to couple light between standard optical fibers and single-mode waveguides in the silicon-on-insulator platform and to split both orthogonal polarization states is presented.
Proceedings ArticleDOI
Tunable liquid crystal Fabry-Perot filters
Wolfgang Vogel,Manfred Berroth +1 more
TL;DR: In this article, a tuneable optical filter based on liquid crystal Fabry-Perot interferometers (LCFPI) is presented, which is suitable for compact arrays with a large number of pixels, as shown in high resolution flat panel displays.
