A connector to an optical fiber comprises a prism 30, a ferrule 50 and an aspheric lens 40. The prism 30 includes a triangular wedge element having a first surface, a second surface and a base. The ferrule 50 guides the optical fiber 10 so as to contact the optical fiber 10 with the first surface of the prism 30. The aspheric lens 40 is integrated on the second surface, the integrated aspheric lens 40 being positioned so that the prism 30 serves to redirect a light beam at an angle relative to an axis of the optical source input through total internal reflection by utilizing the base of the triangle wedge element. The aspheric lens 40 serves to collimate the redirected light beam or focus the light beam before being redirected. This arrangement may, for example, be used within a WDM system to multiplex and de-multiplex several wavelengths of light, using a "zig-zag" optical path configuration and thin film filters to separate the wavelengths. |
