The isolator further includes a first optical fiber collimator 1a being placed at the forward-beam incident side of the first polarization separation element 91 and including a collimating lens 101 and a first optical fiber 31, and a second optical fiber collimator 2a being placed at the forward-beam exit side of the second polarization separation element 92 and including a collimating lens 102 and a second optical fiber 32 connected to a fiber amplifier. Also, an edge filter 100, which transmits light emitted from the first optical fiber 31 and having a wavelength equal to an oscillation wavelength and which reflects light emitted from the first optical fiber 31 and having wavelengths shorter than this wavelength, is placed between the second optical fiber collimator 2a and the second polarization separation element 92.

    摘要： A double stage isolator is formed of face-to-face slabs or sheets of materials that will suitably split, combine, non-reciprocally rotate to ensure isolation in a reverse direction from output ports to respective input ports of any light launched into the input ports. A right angled Porro-prism is disposed at an end of the affixed together slabs having planar faces to direct light launched in a folded fashion to the output ports. A half waveplate is used in addition to beam splitter combiners and non-reciprocal rotators means that rotate the light by 90 degrees so as to pass a single beam in a forward propagating direction and to interchange the polarization of two sub-beams that pass through from an output port to an input port in a reverse direction.

    摘要： Optical signal interleaver/deinterleavers with reduced chromatic dispersion are described. In one embodiment, the interleaver/deinterleavers include two optical filters and an optical isolator coupled to receive the output of each of the optical filters. The optical isolators feed the filtered signals back to the filters. Passing the filtered signals back through the filters in the opposite direction as the first pass allows the filters to cancel, or nearly cancel, the chromatic dispersion caused by the filters on the first pass. Thus, the interleaver/deinterleavers provide reduced chromatic dispersion as compared to use of a single filter or of cascaded filters.

    摘要： The invention provides a semiconductor laser module and an optical transmission system, with which noise caused by light reflected back from a transmission path can be suppressed. The semiconductor laser module, includes a package having a window, a semiconductor laser chip outputting light, a lens that is optically designed such that it couples the light that is output by the semiconductor laser chip into an optical transmission path, an optical isolator that is disposed between the lens and the window, a temperature control mechanism for keeping temperature of these components constant, and a tubular ferrule that is holds and covers the optical transmission path. The semiconductor laser chip, the lens, the optical isolator, and the temperature control mechanism are arranged inside the package. A polarizer is arranged at an end face of the ferrule on the side of the package, such that the polarizer matches a polarization plane of the light that is emitted through the window of the package.

    摘要： Arranged, with spacing, are a first separating/combining birefringent element 10, first and second optical-path controlling birefringent elements 11, 12, and a second separating/combining birefringent element 13. Between the first separating/combining birefringent element and the first optical-path controlling birefringent element, is arranged first polarization rotating means 14 for changing a polarization direction from an orthogonal to a parallel or from a parallel to an orthogonal. Also, between the second optical-path controlling birefringent element and the second separating/combining birefringent element, is arranged second polarization rotating means 17. The first and second optical-path controlling birefringent elements are oppositely arranged symmetric in optical axis about an arrangement center thereof, between which is arranged a null-wavelength plate for rotating 90 degrees a polarization direction of a light on a central optical path, thereby structuring an optical circulator. With a similar structure, an optical switch can be structured by using a null45-degree variable Faraday rotator in the first and second polarization rotation switch means.
