Patent ID: 6996301

Claim:
An optical module comprising: a substrate; an optical component mounted on said substrate; a first optical fiber connected to said optical component for inputting/outputting light to/from said optical component; a fiber sheet including a first resin sheet having an adhesive layer on one side, a second optical fiber wired on said adhesive layer of said first resin sheet, and a second resin sheet attached to said first resin sheet so that said second optical fiber is sandwiched between said first and second resin sheets; and a metal case accommodating said substrate and said fiber sheet; said second optical fiber of said fiber sheet projecting from between said first and second resin sheets and being connected to said first optical fiber, said optical component including at least one pumping laser diode, said substrate having a hole through a portion of the substrate, and said laser diode being insertable through said hole of said substrate and fixed to said metal case, wherein heat generated from said pumping laser diode is dissipated through said metal case.
