Claim:
1. An optical module mounted on a host board, comprising: an optical assembly including a package, a semiconductor light-emitting device, a mirror, and a thermo-electric-cooler (TEC), the package having a frame, a ceiling and a bottom that form a cavity, the frame being made of multi-layered ceramics, the semiconductor light-emitting device emitting signal light toward a direction substantially perpendicular to the bottom of the housing, the TEC mounting the semiconductor light-emitting device and the mirror thereon, the TEC being mounted on the bottom of the housing in the cavity; a heat spreader having a front and a bottom making substantially right angle against the front, the front being attached to the bottom of the package, the bottom of the heat spreader being attached to the host board to dissipate heat generated in the optical assembly to the host board; a holder for fastening the optical assembly assembled with the heat spreader to the host board securely; and a coupling unit coupled with the ceiling of the package of the optical assembly, the coupling unit including a flange, wherein the holder includes a front, a rear opposite to the front, and skirts that form a space into which the heat spreader and the package of the optical assembly is set such that the front of the holder abuts against the flange of the coupling unit, the rear pushes the heat spreader toward the front of the holder and the skirts put the heat spreader therebetween, wherein the holder has front legs and rear legs, the front legs being bent from the front of the holder, the rear legs being bent from the rear of the holder, and wherein the holder provides cuts between the front of the holder and the front legs, and other cuts between the rear of the holder and the rear legs, the front legs being bent at the cuts between the front of the holder and the front legs, the rear legs being bent at the cuts between the rear of the holder and the rear legs.
