Abstract
Disclosed herein are an optical device, such as a connector or mode enlarger, and a method of fabricating the device. The disclosed device includes an optical medium having a first face for, e.g., permanent attachment to a waveguide, a second face for, e.g., a non-permanent connection, and a region between the first and second faces. A non-fiber, connector waveguide is disposed in the region to propagate the single-mode signal from the first face to the second face. The connector waveguide is optically matched to the waveguide at the first face to receive the single-mode signal carried by the waveguide. The connector waveguide includes a taper section such that the connector waveguide is enlarged at the second face to support an expanded beam of the single-mode signal for propagation through the non-permanent connection. In some cases, the taper section receives the single-mode signal from an input section of the connector waveguide to generate an expanded or narrowed beam of the single-mode signal via discrete modulation of waveguide cross-section. An output section of the connector waveguide then supports the propagation of the expanded or narrowed beam of the single-mode signal …
