Chip coupler
WebA fiber to chip coupling connecting an optical fiber to an integrated circuit. A section of fiber is laid on top of the surface of the chip, where the end of the fiber has been cut at an angle to form an angled tip. The angled tip has a flat surface which reflects light down to a waveguide grating coupler disposed on the integrated circuit. Webthe fibers accurately to the couplers and the design and fabrication of fiber to chip couplers. Different adiabatic designs are proposed, fabricated and tested in this thesis in …
