Abstract
An optical subassembly for non-reciprocal coupling of light from a planar optical waveguide output outside the optical subassembly to an optical fiber includes a carrier configured to support the optical subassembly, an optical fiber fixed to the optical subassembly, a focusing optical system consisting two foci with one focus coincident with the input of optical fiber, an optical isolator to transmit light unidirectionally between two foci, an input boundary provided by the carrier to align the optical subassembly with the planar optical waveguide output. In particular, the optical subassembly is operably configured to provide a low transmission loss for light traveling from the planar optical waveguide output to the optical fiber.
