Abstract
A low coherence light-emitting device comprises a semiconductor body with a pair of end faces, The device contains an optical beam path which has an axis of symmetry extending between the end faces. At least one of the end faces is inclined at an angle which is nonperpendicular to the optical axis and the tangent of this angle is greater than or equal to the width of the beam path divided by the length of the body between the end faces. The device may be made by forming at least one of the end faces such that the end face is inclined at an angle relative to a plane perpendicular to the optical axis. The tangent of the angle is greater than or equal to the width of the optical path divided by the length of the body between the end faces.
