要約
(EN)

Included are a metal block, a first sub-mount fixed to the metal block, and a second sub-mount having an upper surface and a lower surface which is fixed to the first sub-mount via a metal layer. Also included are an optical element mounted on the upper surface of the second sub-mount and a high frequency line path which is formed on the upper surface of the second sub-mount and electrically connected to the optical element so as to cause a signal such as a high-frequency signal to be input to or output from the optical element. In addition, the metal layer is electrically connected to the metal block.
