Abstract
A coupling system includes an optical fiber configured to carry an optical signal. The coupling system further includes a chip in optical communication with the optical fiber. An angle between the optical fiber and a top surface of the chip ranges from about 92-degrees to about 88-degrees. The chip includes a grating configured to receive the optical signal; and a waveguide, wherein the grating is configured to receive the optical signal and redirect the optical signal along the waveguide. ms.
