摘要： PROBLEM TO BE SOLVED: To provide a self-forming optical module in which a wavelength selective mirror is used. SOLUTION: The wavelength selective mirror 4 reflects a wavelength λ c1 , transmits a wavelength λ c2 and green light, and reflects red light. An end face 21 of the core of an optical fiber 2 is introduced into a housing 1 composed of transparent resin and is fixed with a fixing member 3 (3. A). Unhardened photosetting resin solution 5 of a high refractive index is charged inside the housing 1. When the photosetting resin solution 5 is irradiated with the laser beam of the wavelength λ c2 from the end face 21, a hardened product 50 is axially formed along the optical path (3. B). With the laser beam of the wavelength λ c1 is emitted from the end face 21, an axial hardened product 51 is formed in a branching manner (3. C). With the unhardened photosetting resin solution 5 removed (3. D), and with the unhardened photosetting resin solution 6 of a low refractive index charged inside the housing 1, all are hardened to form a clad 6c. A green optical element 70 is coupled with a red optical element 71, thereby forming the optical module 100 capable of two-color single-line bidirectional communication that functions on green and red light (3. E). COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an optical device which does not deteriorate in an accelerated degradation test in which repetition is made between a high temperature and high humidity state and a low temperature state. SOLUTION: The optical device includes in the inside of a light transmittable housing 10: a shaft shaped core 30 which is obtained by self convergently photocuring a photosetting resin; and a clad 40 including an organosilsesquioxane, an epoxy resin and an oxetane resin. The epoxy resin and the oxetane resin are increasingly smaller in a curing shrinkage rate than an acryl resin when they are cured, and consequently a tensile stress hardly remains in the inside of the clad 40 which is a formed cured product. The epoxy resin, the oxetane resin and the organosilsesquioxane are high in heat resistance and small in hygroscopicity compared with the acryl resin having an ester bond and are not consequently swollen due to moisture even at a high temperature and high humidity. Furthermore, the light transmittable housing 10 is preferably formed from the epoxy resin and the oxetane resin. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a coupler, which has less optical loss and further minimizes a difference in power between different output ends of the same signal. SOLUTION: When each of half mirrors HM-a, b and c transmits p-wave (Ap, Bp, Bp) 100% and reflects s-wave (As, Bs, Cs) 100%, the s-wave input from In-a reaches Out-c without attenuation. The p-wave input from In-a reaches Out-b without attenuation (2.A). Since the distance between In-a and Out-c is larger than the distance between In-a and Out-b, the loss between the In-a and Out-c is larger than the loss between In-a and Out-b with respect to the loss during transmission of a core composed of a photo-curable resin. In order to balance the powers at different output ends of the same input, 85% of the wave is transmitted by the half mirror HM-b and reaches Out-b. The remaining 15% is reflected by the half mirror HM-b and lost (2.D). Thereby the difference in power between Out-b and Out-c is reduced. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：提供一种耦合器，其具有较少的光损耗，并且进一步使相同信号的不同输出端之间的功率差异最小化。解决方案：当半反射镜HM-a，b和c中的每一个透射p波（Ap，Bp，Bp）100％并反射s波（As，Bs，Cs）100％时，s波输入从In-a达到Out-c而不衰减。 In-a的p波输入达到Out-b无衰减（2.A）。由于In-a和Out-c之间的距离大于In-a和Out-b之间的距离，In-a和Out-c之间的损耗大于In-a和Out-b之间的损耗，相对于由光固化树脂构成的芯的透射过程中的损失。为了平衡相同输入端的不同输出端的功率，85％的波由半反射镜HM-b传输并达到Out-b。其余的15％被半反射镜HM-b反映，并丢失（2.D）。因此，Out-b和Out-c之间的功率差减小。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To obtain a light coupler capable of curing a shaft-shaped core in a manner of self-formation. SOLUTION: In the light coupler, three light input terminals In, three light output terminals Out, three half mirrors HM and a mirror M are connected by an optical waveguide Core. Signal light input from the light input terminal In-a can be taken out with dissipation from the light output terminal Out-b and the light output terminal Out-c.
