Abstract:
A light coupling unit for use in an optical connector includes a waveguide alignment member that receives and aligns at least one optical waveguide. The light coupling unit includes a light redirecting member that has an input surface configured to receive input light from the end face of the optical wave guide. A curved reflective surface of the light redirecting member receives light from the input surface propagating along an input axis and redirects the light such that the redirected light propagates along a different redirected axis. An output surface of the light redirecting member receives the redirected light and transmits the redirected light as output light propagating along an output axis and exiting the light redirecting member. A curved intersection of the curved reflective surface and a first plane formed by the input and redirected axes has a radius of curvature. The curved reflective surface has an axis of revolution disposed in the first plane. The axis of revolution forms a first angle with the redirected axis which is non-zero. The waveguide alignment member is configured such that the end face of the optical wave guide is positioned at a location that is not a geometric focus of the curved reflective surface.
