  4. 2. Multifunctional Waveguide Grating Couplers for Integrated Optics

    Author : Johan Backlund; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis describes a novel waveguide component in integrated optics called a multifunctional grating coupler. It couples light in or out of optical waveguides and provides additional optical functions such as beam splitting, arbitrary focusing, polarization sensing, and wavelength separation (wavelength division demultiplexing).

    Abstract : To follow the trend of the data traffic and to limit the size of the hyperscale data centers, communication solutions offering small footprint, low cost and low power consumption are needed. Optical interconnects used in data centers are mostly short reach (approximately 100 m) based on GaAs-based 850 nm vertical-cavity surface emitting lasers (VCSELs) and OM4 multimode fibers (MMF).
