Abstract: An optical apparatus of the invention has a fusion splice portion where respective ends of two optical fibers each having a core, a cladding, and a UV coat portion provided on the outside of the cladding are fusion spliced, and a re-coat portion which re-coats a portion where the UV coat portion is removed in the vicinity of the fusion splice portion is formed using a material capable of absorbing light radiated from the fusion splice portion. As a result light which is radiated from the fusion splice portion can be reliably prevented from coupling into another optical fiber adjacent to an outside of the re-coat portion.

Abstract: A housing 20 is equipped for supporting, from a side, a platform of a wavelength selection device comprising an input/output port 10, a collimator 11, an expanding optical system 12, a spectroscopic element, a collecting optical system 14 and a micro electro mechanical system (MEMS) mirror array 15. Because the above noted optical member is supported from the side only, influences of a thermal expansion is limited to the height direction of the optical member and the optical axis direction. By these aspects, the influence of thermal expansion is limited to a two-dimensional from a common three-dimensional, thereby enabling a design of a countermeasure to an influence of a thermal expansion. Also, the support from the side does not create a dead space thereby making the wavelength selection device compact.

Abstract: A chromatic dispersion compensator of present invention includes a high-refractive-index VIPA plate, a three-dimensional mirror, and a control unit. The high-refractive-index VIPA plate is made of a material such as silicon having a refractive index higher than that of optical glass and is able to output incident lights toward different directions according to wavelength. The three-dimensional mirror reflects the light of each wavelength emitted from the high-refractive-index VIPA plate, at a predetermined position and returns the light to the VIPA plate. The control unit controls a temperature of the high-refractive-index VIPA plate at a constant level while controlling the position of the three-dimensional mirror corresponding to a chromatic dispersion compensation amount. Thereby, larger chromatic dispersion can be compensated while a decrease in transmission bandwidth is suppressed.

Abstract: The optical receiver includes: an optical input port for receiving WDM signals; a transmittable-wavelength-variable filtering unit which transmits, of the received WDM signals, a light signal in a predetermined transmittable wavelength bandwidth with a desired central wavelength of λi (i=1 to n: n is an integer number greater than 2); an optical output port which outputs the remaining light signals at wavelengths (λi) (k=1 to n; k≠i) untransmittable through the transmittable-wavelength-variable filtering unit; and a control unit which controls the central wavelength so that the level of the light signal passing through the transmittable-wavelength-variable filtering unit is the maximum. It is whereby possible to flexibly accommodate changes in number of channels combined in a WDM system, and to adaptively minimize ASE light leaking into the photoreceptor of the optical receiver even in a CWDM system with wide channel spacing.
