摘要： An apparatus provided with a polarizer in which, among the transmission surfaces for the beam of light at a transparent substrate (14), the transmission surface (14a) on which a polarizing isolation film (4) is not formed, is slantwise disposed to that (14b) on which the polarizing isolation film (4) is formed, and transmitting the beam (12) of parallel light of a predetermined incident angle to thereby perform polarizing isolation. An optical isolator is provided with the two apparatus, and therebetween with a Faraday rotor.

摘要： In connecting an optical fiber (15) to an optical waveguide (12) formed in a waveguide substrate (11), a first groove (13) is formed in the substrate to expose one end of the optical waveguide (12), and a second groove (14) is formed at right angles with the first groove. The optical fiber is fitted into the second groove in a manner that the end surface of the optical fiber (15) is brought into intimate contact with the end surface of the optical waveguide (12), and the optical fiber is secured in the second groove with an adhesive. Thus, there is provided a method of connecting the optical fiber and the optical waveguide together maintaining excellent temperature characteristics and impact resistance.
摘要翻译：在将光纤（15）连接到形成在波导基板（11）中的光波导（12）的同时，在基板上形成第一凹槽（13）以露出光波导（12）的一端，而第二凹槽槽（14）与第一槽成直角。光纤以使光纤（15）的端面与光波导（12）的端面紧密接触的方式嵌入第二槽中，光纤固定在第二槽用粘合剂。因此，提供了一种将光纤和光波导连接在一起，保持优异的温度特性和抗冲击性的方法。
