Patent number: 7603008Abstract: An optical fiber coupling part that reduces the difficulty in adjusting cores, minimizes coupling loss, and prevents optical characteristics from deteriorating. An optical fiber is fused to one end of a GRIN lens which includes a quartz glass containing one or more refractive index regulating substances selected from Sb2O3, Ta2O5, TiO2 or ZrO2. Optical characteristics are not deteriorated because an adhesive is not used, and self-alignment effects facilitate adjustment of the cores of the GRIN lens and the optical fiber. Furthemore, coupling loss can be minimized by setting a refractive index distribution constant g of the GRIN lens within an appropriate range.Type: GrantFiled: February 1, 2005Date of Patent: October 13, 2009Assignee: Toyo Glass Co., Ltd.Inventors: Hiroyoshi Matsumura, Taro Suzuki, Toru Achiwa

Patent number: 7346237Abstract: An optical fiber coupling part capable of reducing coupling loss while maintaining a large operating distance, and having a good module assembling property. AT least one GRIN lens having numerical aperture NA that is larger than numerical aperture NAs of a light-emitting source (such as a semiconductor laser) is fusion-spliced with one end of the optical fiber.
