    摘要： A lens array (38) is mounted on the front surface of an optical fiber array (32) holding optical fibers (35, 36) for input and emission. The lens array (38) includes: an input lens (40a) for converting a signal light (45) emitted from the optical fiber (35) into parallel light or converged light; and an output lens (40b) for converging the returned parallel light and connecting it to the optical fiber (36). A rectangular prism (34) having a form of a rectangular equilateral triangle is arranged in front of the optical fiber array (32) having the lens array (38). The signal light (45) emitted from the optical fiber (35) is totally reflected twice by the rectangular prism (34) and comes into the optical fiber (36). A transparent rectangular rotary block (33) is arranged between the lens array (38) and the rectangular prism (34). The outgoing signal light (45) and the returning signal light (45) have optical axis shifted by the rotary block (33) where the signal light passes. With this structure, it is possible to obtain a small-size variable light attenuator having a high control accuracy of the attenuation quantity of the signal light and a high resolution.

    摘要： [Object] A monitoring device for precisely taking out light for a monitor and having a simple structure and able to be made compact is provided. [Means for Resolution] A lens array 17 is attached to the tip face of an optical fiber array 12 holding optical fibers 14, 15 in parallel. A lens 19 is arranged in the lens array 17 so as to be opposed to the end face of each of the optical fibers 14, 15. A triangular prism 13 is arranged in front of the lens array 17. An incident-emitting face 22 of the triangular prism 13 is inclined with respect to the lens array 17. Signal light L emitted from the optical fiber 14 is converted into parallel light by the lens 19, and is incident to the triangular prism 13. After the signal light L is then totally reflected on the reflecting face 20, the signal light L is incident to a reflecting face 21. The incident angle of the signal light L incident to the reflecting face 21 is slightly smaller than a critical angle of the total reflection. The signal light L is leaked from the reflecting face 21 to the exterior by a constant ratio κ. Accordingly, the amount of the signal light L can be calculated by measuring this leak light La.

    摘要： The present invention provides an optical multiplexer/demultiplexer which can demultiplex a multiplexed optical signal having a number of wavelength bands into respective wavelength regions, or multiplex light having respective wavelength regions in the field of optical communications. That is, light gained by multiplexing light having wavelengths λ1, λ2, λ3 and λ4 is emitted from an optical fiber (9a) and the optical axis thereof is bent by a micro lens (12a) of a micro lens array (14) so that the light is converted to parallel light which is then reflected from a mirror layer (19) so as to enter into a filter layer (17). A filter (17a) transmits only light having wavelength λ1, and light having other wavelengths is reflected and again reflected by the mirror layer (19) so as to enter into the filter layer (17). The optical axis of light that has transmitted through the filter (17a) is bent by a micro lens (12c) so that the light is coupled to an optical fiber (9c). Light having wavelength λ1, λ2, λ3 and λ4 is taken out from the light emitting ends of optical fibers (9c, 9d, 9e and 9f), respectively.
