摘要： PROBLEM TO BE SOLVED: To provide an optical connecting component having a built-in fiber grating that gives desired optical characteristics upon connecting another optical connecting component having a built-in regular optical fiber. SOLUTION: An optical adaptor 1 has an optical fiber 11 having a fiber grating 10 formed therein. The fiber grating 10 has a first grating region formed in one end side of the optical fiber 11 and a second grating region formed in the other end side of the fiber 11. The second grating region is preferably formed as continuous to the first grating region. The first grating region is formed in such a manner that the grating pitch gradually increases from one end side of the fiber 11 to the other end side, while the second grating region is formed in such a manner that the grating pitch gradually decreases in the same direction.

摘要： PROBLEM TO BE SOLVED: To provide a polarization-maintaining multi-core optical fiber having a smaller diameter and a high density core arrangement and capable of suppressing inter-core crosstalk.SOLUTION: A polarization-maintaining multi-core optical fiber 1 with elliptical cores 11 causes structural birefringence, which allows a linearly polarized light wave with a matching direction of polarization main axis with each core of the multi-core optical fiber to propagate without altering the polarization state thereof, thereby eliminating the need for a stressor or the like which is required for ordinary polarization-maintaining multi-core optical fibers. This enables high density core arrangement within a fixed cladding cross-section. Further, directions of lines connecting the centers of the most adjacent cores are arranged to be different from the longitudinal directions of field distributions (i.e., longitudinal directions of the elliptical cores) to reduce overlap of field distributions between the most adjacent cores, which reduces inter-core crosstalk compared to an arrangement where the directions of lines connecting the centers of the most adjacent cores are arranged to be the same as the longitudinal directions of the field distributions.

摘要： PROBLEM TO BE SOLVED: To provide a wavelength selection switch capable of suppressing coupling of secondary reflection light with an output port when coupling primary reflection light with the output port.SOLUTION: Since each value is set so as to satisfy a formula (θ>2×θ+α), the wavelength selection switch can move secondary reflection light to be away from an output port when moving primary reflection light so as to vary a tilt angle of a mirror during operation to approach the primary reflection light to the output port and suppress coupling of the secondary reflection light with the output port when varying the tilt angle of the mirror to couple the primary reflection light with the output port.
