摘要： A low coherence light emitting device comprises a semiconductor body with pair of opposed end faces. The device contains a current confining structure which forms an effective optical beam path between the end faces. The current confining structure is inclined at an angle relative to the direction perpendicular to at least one of the end faces. The tangent of this angle is greater than or equal to the effective optical beam path divided by the length of the body between the end faces. The structure thereby forms a device in which off-axis reflection is obtained at at least one of the device's end faces.
