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.

摘要： A first light reflection surface (51) and a second light reflection surface (52) are formed on a lower half of a mirror block (50) in a state that these light reflection surfaces (51), (52) make 90 degrees therebetween. A first light reflection surface (51) and a second light reflection surface (52) are also formed on an upper half of the mirror block (50) in a state that these light reflection surfaces (51), (52) make 90 degrees therebetween. A third light reflection surface (53) and a fourth light reflection surface (54) are formed between the first light reflection surface (51) and the second light reflection surface (52) such that these light reflection surfaces (53), (54) make 90 degrees therebetween. According to this optical switch, by changing a region which reflects the light between the upper half and the lower half of the mirror block (50), the coupling relationship between an input optical fiber and an output optical fiber can be changed over.

摘要： To decrease an insertion loss by shortening an optical path length between an input side optical fiber and an output side optical fiber, and to decrease a stroke of a drive component. Input side optical fibers and a preliminary optical fiber arranged in parallel to one another and output side optical fibers arranged in parallel to one another are arranged in two stages, and a fixed prism 14 is arranged to be opposite to end surfaces of these. A preliminary optical fiber prism 15b is provided on one oblique surface of the fixed prism 14 to be opposite to a preliminary optical fiber 20, and a driven prism 15a can be made to come in contact with and separated from the one oblique surface of the fixed prism 14, and the driven prism 15a can be moved along the input side optical fibers. At a position where the driven prism 15a comes in contact with the oblique surface of the fixed prism 14, outgoing light from the input side optical fiber is not totally reflected at the oblique surface of the fixed prism 14, but is incident on the driven prism 15a, and after it is sent from the driven prism 15a to the preliminary optical fiber prism 15b, it is incident on the preliminary optical fiber 20 from the preliminary optical fiber prism 15b.

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.
