    摘要： A conventional problem is to provide an optical module capable of being reflow mounted together with electronic components collectively, and, at the same time, securing a mechanical strength that can bear a large stress at the time of an attachment/detachment of the optical fiber. A solution to the above-mentioned problem can be attained by using an optical connector removable type optical module for reflow mounting having a fixing structure for fixing itself to a mount board, including a receptacle part installed to an optical module 19 to which an optical connector 1 is detachably connected; electric terminals 4 for reflow mounting that are arranged corresponding to lands 8 on a mount board 6; and stud parts 5 that are able to fit in fixing holes 7 on the mount board 6.

    摘要： A passive region is provided on one side or both sides of a waveguide-type optical modulator. Thereby, it is possible to obtain a high-speed optical modulator package superior in mechanical strength, thermal characteristic, high-frequency characteristic, and extinction characteristic. Moreover, it is possible to increase the operating speed of an optical fiber transmission equipment by applying the optical modulator package to the optical fiber transmission equipment.

    摘要： The present invention provides an optical module using optical waveguides which permits easy fabrication of a PLC type optical multiplexer/demultiplexer with reduced loss. The optical module comprises cores which are contiguous to each other through a dicing groove adapted to position and fix an optical functional part such as a wavelength selection filter and a core branched from the said cores. A slight gap is present between the former and the latter core and both cores are narrower in width in the vicinity of the dicing groove than the other portions.
