1. An optical semiconductor module adapted to a plurality of optical transmission and reception channels, comprising:

  • a monocrystalline substrate having first and second surfaces;

    an optical semiconductor array formed on the first surface of the monocrystalline substrate, having a plurality of optical axes, for performing light emitting and receiving functions;

    an optical fiber array formed on the first surface of the monocrystalline substrate, having a plurality of optical axes, for transmitting light received and emitted by the optical semiconductor array;

    an optical axis aligning mechanism, formed on the first surface of the monocrystalline substrate, for aligning the optical axes of the optical semiconductor array with the optical axes of the optical fiber array;

    an airtight sealing member formed on the first surface of the monocrystalline substrate for forming an airtight seal around the optical semiconductor array and a portion of the optical fiber array; and

    a reinforcing body formed on the second surface of the monocrystalline substrate and thermally connected to a part of the airtight sealing member, and having a thermal expansion characteristic substantially equal to that of the airtight sealing member.
