<P>PROBLEM TO BE SOLVED: To provide an optical receiver of simple configuration, with wide light receiving angle and high coupling efficiency. <P>SOLUTION: A light receiving element 120 is arranged between a second lens surface 102 and a focal point Fp1. The light that does not directly enter the light receiving surface 121 of the light receiving element 120 is reflected on a mirror 130 and a reflective part 110, and then enters the light receiving surface 121. <P>COPYRIGHT: (C)2007,JPO&INPIT |
