A substrate (101) is etched by etching processing with crystal anisotropy, thereby forming a recess (104) from the main surface of the substrate (101) to the inside of the substrate (101). A side surface (105) is almost a (111) plane, and the etching hardly progresses. As a result, a cross section of the recess (104) perpendicular to the longitudinal direction has a rectangular shape. Since an opening (103) of a mask pattern (102) has a rectangular shape in a planar view, the opening of the recess (104) has a rectangular shape in a planar view, and the recess (104) is formed into, for example, a rectangular parallelepiped shape. The recess (104) includes a side surface (105) that forms one plane perpendicular to the main surface of the substrate (101). The side surface (105) is a facet surface and is a tilting surface tilted from the (111) plane.

The distal end face (51) has a first inclined surface (56) and a second inclined surface (57) forming the distal end portion of the tip (44) into a mountain shape in cross section, and has a convex curved surface (58) for connecting them to the outer circumferential surface (52). The first inclined surface (56) crosses an axis of the tip (44), and inclines at an angle smaller than an inclination angle of a distal end face of an APC connector. The second inclined surface (57) is formed such that an offset line (61) (a ridgeline) at the distal end of the tip (44) is positioned between the axis of the tip (44) and the winding hole (54), and inclines at an angle equal to or larger than the inclination angle of the distal end face of the APC connector. The convex curved surface (58) inclines at an angle equal to or larger than the inclination angle of the distal end face of the APC connector. This makes it possible to provide an optical connector cleaning tool capable of properly cleaning both a PC connector and an APC connector without using a rotation mechanism for rotating a tip.
This optical connector (10) comprises a front-stage block (11) in which optical fibers are mounted, a rear-stage block (12) in which a polymer waveguide is mounted, a self-forming waveguide (18) that is disposed between the front-stage block and the rear-stage block and connects the optical fibers and the polymer waveguide, and a cladding part (19) formed on the periphery of the self-forming waveguide, the self-forming waveguide being a portion, cured by irradiation with a resin curing light, of a self-forming waveguide material that is disposed between the front-stage block and the rear-stage block. Through this configuration, the present invention can provide an optical connector in which loss of connection between optical fibers and a polymer waveguide is reduced by a simple structure.

Accordingly, when the body (12) rotates, the rotating pod (40) and the rotational axis rotate to cause the cleaning thread (41) that has been pulled out over an end surface of a cleaning section (S) of the rotational axis to clean a connecting surface (4a or 91a) of the optical connector (3 or 90). The rotating pod (40) pulls out the cleaning thread (41) from the supply reel and winds it into the wind reel through rotation.
An optical connector (1) is provided with a holding part (2), a cleaning part (5), and a cap (6). The holding part (2) is provided with: a cylindrical slider (10), a cylindrical body (12) disposed so as to be freely rotatable with respect to the slider (10) and freely movable in the direction of the axis, a slider-recovering spring (13) that biases the slider forward and restores the slider to the initial position, and the like. The slider (10) has a pair of elastic pieces (16) that are provided with guide projections (17). On the periphery of the body (12) are formed spiral grooves (25, 26) that engage the guide projections (17) over an angular range of 360°. When the slider (10) moves forward, the body (12) rotates due to the camming action of the guide projections (17) and the spiral grooves (25, 26). The cleaning part (5) is connected to the body (12), and is provided with a cleaning string (41), a supply reel (42), a take-up reel (43), a cleaning pin (44), and the like, which are arranged inside a rotating pod (40). The rotating pod (40) and the cleaning pin (44) rotate with the body (12), and the cleaning string (41), which is pulled out to the apical surface of the cleaning pin (44), cleans the connecting surface of the optical connector. The cleaning string (41) is pulled out from the supply reel (42) due to tension applied by the rotation of the cleaning part (5), and is reeled in by the take-up reel (43).

In order to increase the diffraction efficiency by forming a multi-layer film on a laminar type diffraction grating surface, it is necessary to satisfy four conditions: [1] condition of a groove depth capable of obtaining the optimal reflectivity; [2] extension Bragg condition of the multi-layer film; [3] condition expression defining correlation between directions of an incident light and a diffracted light; and [4] a ratio of the width of convex portion against the concave portion on the laminar type diffraction grating surface. However, there has been no unified design guideline. The present invention solves this problem by giving a general design guideline and an optimal multi-layer substance pair so as to provide a diffraction grating having both of a high diffraction efficiency and a high resolution in the wavelength region of 0.1 to 1 nm where spectroscopy using a diffraction grating is difficult because of the efficiency lowering.
