PROBLEM TO BE SOLVED: To provide an optical module exhibiting further improved transmission density (transmission throughput) and capable of driving in various modes suitable for driving at not more than 10 Gbps/channel or high-speed driving at 40 Gbps, 100 Gbps or the like, responding to broadening of optical data transmission from a long distance to a short distance in the optical communication field in recent years. SOLUTION: In the module, an upper structure having an optical transmission path such as an optical waveguide 7 and an optical element-electronic component mounting substrate mounting optical elements and electronic components are fixed by pressing in a perpendicular direction onto a wiring board by use of an attachment body such as a fastening member so as to achieve optical and electric connection. In the module, an end portion of the optical waveguide 21 is provided with at least either a light entrance portion 21a or a light exit portion 21b branched into two; and the branched light exit portions 21b are provided with wavelength selective filters 24-1 and 24-2, respectively so as to carry out multiplexed optical transmission and reception using light at two different wavelengths. The optical elements and the electronic components are electrically connected to the optical element-electronic component mounting substrate by flip-chip connection. COPYRIGHT: (C)2009,JPO&INPIT |
