摘要： A thin film type resistor is disclosed. The thin film type resistor comprises first and second pads, a first resistance layer, and a second resistance layer. The first and second resistance layers are spaced apart from each other. Both ends of a first resistance layer are connected to the first and second pads. A second resistance layer is disposed on the first resistance layer, and has a resistance value different from that of the first resistance layer.

摘要： A semiconductor optical package for optical communication includes a cooling plate dissipating internal heat generated from the semiconductor optical package and having one or more grooves passing through top and bottom surfaces thereof. There is a housing having one or more slots formed on its bottom face, the housing at least partly enclosing an optical transmission module resting on the cooling plate such that the respective slots thereof correspond to the respective grooves of the cooling plate. There are also one or more screws passing through the grooves and inserted into the slots for coupling the housing to the optical transmission module.

摘要： 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.
