When asked, many well-trained scientists and engineers will say that they understand what a mode is, but will be unable to define the idea of modes and will also be unable to remember where they learned the idea!. Today we will discuss how we can couple light between optical fibers and on-chip photonic waveguides. In particular we will focus on grating couplers.. Today we will cover the theory of grating couplers. Next week we will put the theory to use and design a silicon photonic grating coupler. Possible improvement of the CLIC accelerating structure. From CLIC_G to CLIC_K. 2 .07.2009 Alexej Grudiev CERN Outline Current CLIC accelerating structure: CLIC_G Compact coupler design with damping The simplest optical communication scheme is single wavelength / channel communication.. The light from a single laser (VCSEL, DFB laser, etc.) is electrically-modulated and sent through a single or multimode fiber..
