Abstract:
1. A fiber collimator unit, comprising: a first focusing element having an optical axis and a first focal length; a first optical fiber optically coupled to a first side of the first focusing element, the first optical fiber being disposed at a first transverse distance from the optical axis so that light from the first optical fiber propagates on a second side of the first focusing element as a substantially collimated beam at a first angle to the optical axis; a wedged optical element optically coupled to the second side of the first focusing element, the wedged optical element deviating the substantially collimated beam so as to propagate in a direction substantially parallel to the optical axis, the wedged optical element including a reflecting surface to reflect light from the first fiber to a second fiber disposed on the first side of the first focusing element; and a deviating plate disposed on a side of the wedged optical element away from the first focusing element to deviate the substantially collimated beam that is transmitted through the wedged optical element.
