摘要： An optical combiner in which the number of parts used is lessened is made of a resin. The optical component comprises a first surface, a diffraction grating, and a second surface. The first surface is a surface providing first, second, and third lenses. The diffraction grating diffracts to a common optical path leading to the second surface light of the first wavelength incident on the first lens, light of the second wavelength incident on the second lens, and light of the third wavelength incident on the third lens. The second surface emits light incident thereon through the common optical path. The optical path from the first surface to the diffraction grating and the common optical path are constituted of the resin.

摘要： A diffraction grating portion (12) is formed in an optical fiber (10), having a diameter of 125 .mu.m and serving to transmit light, along its optical axis. The optical fiber is concentrically surrounded by a lower coating portion (14) having an outer diameter of 300 .mu.m and consisting of a silicone resin. The lower coating portion is concentrically surrounded by a coating portion (16) having an outer diameter of 900 .mu.m and consisting of a liquid crystal polymer, e.g., polyester amide. The coating portion is further surrounded by an outermost coating portion (18) having an outer diameter of 1 mm and consisting of a UV curing resin colored for identification. Both the optical fiber (10) and the lower coating portion (14) have positive thermal expansion coefficients.

摘要： An optical connecting member realizes an optical connecting between a multi-core fiber and a plurality of single-core fibers by a waveguide part which connects a first end face and a second end face. With the optical connecting member, a connected end which is connected to the first end face is a straight-line portion that is orthogonal to the first end face in each of the plurality of waveguide parts. In addition, a diverged end which is diverged to the second end face is a straight-line portion that is orthogonal to the second end face. Consequently, light that has passed through the waveguide parts is emitted from the first end face and the second end face substantially perpendicularly to the faces, thereby enabling optical connecting loss to be favorably inhibited.

摘要： The present invention relates to an optical waveguide type grating element and others in structure for decreasing absolute values of chromatic dispersion occurring in selective reflection of each of signal channels in a reflection band. The optical waveguide type grating element is provided with an optical waveguide in which signal light containing a plurality of signal channels spaced at a channel spacing λi propagates, and a grating which is an index modulation formed over a predetermined range of the optical waveguide. Particularly, the optical waveguide type grating element has a transmittance of −20 dB or less for each of the signal channels in the reflection band, and has a reflectance of −20 dB or less for each of signal channels outside the reflection band. Furthermore, a deviation of a group delay time of each of the signal channels in the reflection band, which is caused by reflection in the grating, is 10 ps or less in a wavelength range of (λCH−λi×0.375/2) or more but (λCH+λi×0.375/2) or less, where λCH is a center wavelength of each signal channel.
