The optical multiplexer/demultiplexer 100 includes a member 110 on which optical waveguides 111 to 114 and a groove 115 are formed and an optical filter 120 inserted in the groove 115. The member 110 is a planar optical waveguide where the optical waveguides 111 to 114 are formed on one surface thereof, and the groove 115 is formed thereon. Before the groove 115 is formed, the optical wave guide 111 and the optical waveguide 114 are a continuous optical waveguide; and the optical waveguide 112 and the optical waveguide 113 are a continuous optical waveguide. A straight groove 115 is formed so as to go through an intersecting point of the two continuous optical waveguides. The optical waveguides 111 and 114 are formed straightly on the member 110.

摘要:
The present invention relates to an optical communication system of a structure permitting the communication carrier side to select a delivery service content to be finally provided from a terminal in a communication network through an optical fiber to a subscriber home. The optical communication system comprises a terminal as a final repeater in a predetermined communication network for delivering signal light with multiple signal channels multiplexed, to a plurality of subscriber homes; and an optical fiber network with one or more branch points installed between the terminal and the subscriber homes. The terminal includes an optical multiplexer/demultiplexer for multiplexing multiple signal channels included in the signal light, and the branch point is provided with a wavelength selector for selecting at least one of the multiplexed signal channels in accordance with a delivery service content of each subscriber home included in a delivery target group of the terminal and for delivering it to the subscriber home.
摘要:
An optical device has first and second non-parallel optical paths, and a light reflecting surface. The reflecting surface may have a first and second planar portion. The first planar portion receives light from the first path to reflect the light toward the second path. The second planar portion may form an angle θ1 with the first planar portion. Angle θ1 satisfies a condition of 175°≦θ
摘要:
A movable mirror device has a plurality of reflecting mirrors and a plurality of mirror drivers. The plurality of reflecting mirrors are reflecting mirrors to reflect signal light and are arranged in a one-dimensional direction along a predetermined plane. The plurality of mirror drivers are arranged two-dimensionally relative to the one-dimensional direction and individually drive the respective reflecting mirrors.

[Problems to be solved] To provide an optical switching device which can switch between input/output optical paths of input/output ports while suppressing the influence on optical signals passing through other input/output ports.[Means to solve problems] An optical switching device comprises an optical switch array 6 for switching between input/output paths of a plurality of input/output optical fibers. The optical switch array 6 comprises a substrate 8, on which a cantilever 11 is supported. A part of the cantilever 11 on the leading end side is provided with an annular support 12, which supports a movable mirror 7 inclinably. The movable mirror 7 reflects an optical signal from any of the input/output optical fibers toward another input/output optical fiber. The leading end of the cantilever 11 is provided with a comb part 14. Arranged on the upper face of the substrate 8 are electrode 15a, 15b for tilting the movable mirror 7 with respect to the annular support 12 and an electrode 16 for moving the movable mirror 7 in the direction different from the tilting direction of the movable mirror 7.
