    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： Two mirrors (15) and (16) making an angle of 90 degrees are formed on a front face of a mirror member (17). An optical fiber for input (12) and an optical fiber for output (13) are held in a fiber array (14) with a predetermined interval, and an emission lens (23) and an injection lens (24) are provided on a front face of the fiber array (14) in a way that they are opposed to end faces of the optical fiber for input (12) and the optical fiber for output (13) respectively. According to the variable optical attenuator, when the mirror member (17) is straightly moved by an actuator (18), light attenuation can be varied thereby.

    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.
