Abstract
A method of using a coupling system includes aligning an optical fiber with a cavity in a chip, wherein aligning the optical fiber comprises orienting the fiber within an angle ranging from about 88-degrees to about 92-degrees with respect to a top surface of the chip. The method further includes emitting an optical signal from the optical fiber. The method further includes redirecting the optical signal into a waveguide using a grating positioned on an opposite side of the cavity from the optical fiber.
