摘要: The light which is input from an optical fiber to a first port is output to an optical path. The light which is input from the optical path to a half mirror is branched into two, and is output to the optical paths. The light which is output to the optical path reaches to and is reflected from a first reflecting mirror, and returns to the half mirror by an optical path. The light which is input to the half mirror by the optical path is branched into two, and is output to the optical paths. The light which is output to the optical path reaches to and is reflected from a second reflecting mirror, and returns to the half mirror by an optical path. The light which is input to the half mirror by the optical path is branched into two, and is output to the optical paths. The light which is output to the optical path is output from a second port to an optical fiber, and the light which is output to the optical path is output from a third port to an optical fiber.

摘要: A first optical system (11) has a first beam splitter (211). The first beam splitter (211) splits light arriving through a first optical path (P1) into two light beams, and outputs one light beam to a second optical path (P2) and the other light beam to a third optical path (P3). A second optical system (21) outputs the light output from the first beam splitter (221) to the second optical path (P2) and arriving at the second optical system (21) upon giving the light an intensity change with wavelength dependence and a phase change, and has a second beam splitter (221), first reflecting mirror (223), and second reflecting mirror (222). This makes it possible to provide an optical filter (200) which can realize a characteristic excellent in isolation with a very simple arrangement.

摘要: An interleaver is provided with an optical system configured to split light having traveled from a first port to a half mirror, into two beams and direct the beams toward first and second reflectors, respectively. Light reflected by the first reflector and arrived at the half mirror is split into two beams and directed toward second and third ports, respectively. Light reflected by the second reflector and arrived at the half mirror is split into two beams directed toward the second and third ports, respectively. An etalon filter configured to cause a loss on either one of light incident thereto from the first port and the beams directed toward the second port and toward the third port.

摘要: In a polarized wave interleaver 100, signal light of a first wavelength band Λ1 of polarized light component in a first orientation, which enters an input port 111, proceeds to a first path P1 through a first polarized wave separation element 131. Even after passing through a wavelength filter 140, the polarized light component in the first orientation is maintained as it is. And the light proceeds to a third path P3 through a second polarized wave separation element 132, and is output from a first output port 121. Signal light of a second wavelength band Λ2 of polarized light component in a second orientation, which enters the input port 111, proceeds to a second path P2 through the first polarized wave separation element 131, and is converted to the polarized light component in the first orientation by the wavelength filter 140. And the light proceeds to a fourth path P4 through the second polarized wave separation element 132, and is output from a second output port 122. The wavelength filter 140 includes a first multi-refraction material 141, a second multi-refraction material 142 and a third multi-refraction material 143. The optical thickness of the three multi-refraction materials 141-143 has a predetermined ratio; and the orientation of the C axis falls within a predetermined range.
