<P>PROBLEM TO BE SOLVED: To emit a blue or green light beam of small spot diameter and small incident angle. <P>SOLUTION: In the semiconductor light emitting device of surface light emission, a Bragg reflection mechanism comprising DBR multi-layer reflectors 64 and 69 on upper and lower layers sandwiching an active layer 66 is provided to restrict light emitting patterns by light quantum containment effect by the Bragg reflection mechanism. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
