ABSTRACT:
A light branching element or diplexer comprising a first bi-directional light connection and a second and third unidirectional light connection. The unit is formed by a block having a straight surface groove with an embedded glass fiber which fiber is interrupted by a partially transmissive mirror lying on a slanting plane relative to the axis of the fiber. The light sensitive location of a light receiving semiconductor element is secured to the block adjacent to the mirror and the plane of the mirror is selected so that its normal extends out of the block at an angle of incidence smaller than 45.degree. to the axis of the fiber to reduce reflections from the semiconductor member back to the mirror and into the fiber.
