Patent number: 6726375Abstract: An optical module for an optical device and an optical fiber is constituted by a pre-molded plastic package. In forming the plastic package, the main flowing direction of the molding resin is substantially parallel with the optical axis of the optical fiber. The optical module is formed by molding the resin by injection using pressure and then solidifying the resin. When the plastic package is formed by comprehensive molding, the flowing direction of the resin is parallel with the optical axis direction of the optical fiber to be installed in the optical module. As a result, for comprehensive molding, the molding pressure applied to the optical fiber is reduced. By using the resin case that is formed, the resulting package exhibits high rigidity and low thermal expansion properties in connection with the flowing direction of the resin, thus reducing the external stress and thermal stress applied to the optical fiber.Type: GrantFiled: August 16, 2002Date of Patent: April 27, 2004Assignee: Hitachi, Ltd.Inventors: Takeshil Kato, Koji Yoshida, Toshinori Hirataka, Toshiaki Ishii, Kazuyuki Fukuda, Tadaaki Ishikawa, Toshimasa Miura, Tsutomu Kono, Kimio Tatsuno

Patent number: 6332720Abstract: When an optical system is housed in a plastic case, an optical connection in the system might be changed by a deformation of the case due to heat and thermal resistance might be increased. It is important that the case has not only a function of housing the elements of the optical system, but also a function of ensuring that light is stably produced in the optical system, which, is the most important function of the case. Therefore, the deformation of the case due to a change in temperature is prevented by a frame inserted into the opening portion of the case and further by mounting the case on an external aluminum substrate. That is, stability in the optical connection is improved by improving the structure of the case and by mounting an case on the external substrate. Further, an increase in the thermal resistance is prevented in the same way by provision of the frame and the external aluminum substrate.Type: GrantFiled: September 16, 1999Date of Patent: December 25, 2001Assignee: Hitachi, Ltd.Inventors: Makoto Shimaoka, Tadaaki Ishikawa, Kazuyuki Fukuda, Katsumi Kuroguchi
