PROBLEM TO BE SOLVED: To provide an optical module capable of reducing an interval of a core between channels of an optical waveguide and reducing cross-talk in an optical coupling part. SOLUTION: On a substrate 1, a light emitting element array 2 consisting of VCSEL 20A to 20D and a light receiving element array 30 consisting of PD 30A to 30D form a gap g and are mounted so that the VCSEL 20A to 20D and the PD 30A to 30D element arrays become parallel with each other, and a mirror on the light emission side and a mirror on a light reception side of the optical waveguide 7 are optically coupled on the VCSEL 20A to 20D and the PD 30A to 30D. The mirror on the light emission side and the mirror on a light reception side of the optical waveguide 7 are arranged so as to form a gap G equal to the gap g. Thereby, the cross-talk on the optical coupling part can be reduced. COPYRIGHT: (C)2009,JPO&INPIT |
