| 英文摘要 | PURPOSE:To prevent positional displacement due to thermal expansion by forming a section elastically deformed in the direction rectangular to the optical axis of a coupling lens to a member shaping a fixing frame. CONSTITUTION:Slits 41, 42 are cut to a member 4 fastening a semiconductor laser 1 and a coupling lens 2 by a fixing frame consisting of the combination of a member 3 and the member 4, and structure in which thermal expansion is absorbed is shaped. The difference of thermal expansion is generated by a temperature change, and force is generated on a coupling surface, but displacing force on the coupling surface is reduced largely by the slit 42, and the laser 1, the lens 2 and the fixing frame can be clamped sufficiently without generating slips by coupling by screws. The stiffness of the member 4 can be changed arbitrarily by altering the slotted depth and space of the slits 41, 42, thus giving elasticity sufficient for absorbing the difference of thermal expansion. |
