    • Disclosed is an optical module of an isolator structure including a semiconductor laser, a polarizer, and a Faraday rotator. The laser outputs a first linearly-polarized beam of a predetermined polarization mode. The polarizer is positioned to face an end of the laser, and its polarization axis is tilted at a 45° angle with respect to the polarization direction of the first beam. The Faraday rotator is disposed between the laser and the polarizer, and rotate the polarization direction of the first beam by 45° to substantially coincide with the polarization axis of the polarizer, and then output it to the polarizer, and to rotate a second beam from the polarizer by 45°, wherein the second beam has a polarization mode polarized perpendicular to the first beam, and then output it to the semiconductor laser.

    • A semiconductor die package having an enhanced degree of heating radiation from the semiconductor, thereby reducing mechanical and electrical failure from excessive temperatures. A semiconductor die has circuit patterns formed thereon; a bump pad deposited on the semiconductor die and supporting at least one of the bumps electrically connected to the circuit patterns; and a radiating pad formed on an upper surface of the bump pad such that the radiating pad surrounds the bumps. An embedded printed circuit substrate includes a radiating pad formed on the bump pad to surround the bumps; and a core substrate has a through-hole formed in the core substrate, that extends from an upper surface of the core substrate to a lower surface thereof. The semiconductor die is deposited on the upper surface of the core substrate such that the bumps extend through the through-hole.
