Abstract: PURPOSE: A semiconductor fiber amplifier integration type wavelength converter is provided to perform easily broadband wavelength conversion and control arbitrarily a width of an output signal by integrating a semiconductor fiber amplifier and a DFB laser. CONSTITUTION: A semiconductor fiber amplifier(100) has a predetermined gain fixed point and amplifies an input optical signal. A DFB(Distributed FeedBack) laser(110) has another gain fixed point and oscillates the amplified signal to a single wavelength. An electrical separator(120) separates electrically the semiconductor fiber amplifier(100) and the DFB laser(110). A buried active waveguide(130) has a multi-quantum well structure. A grating(140) is formed on the edge portion of the buried active waveguide(130) and reflects or transmits the light.

Abstract: PURPOSE: A method for measuring a sectional reflexibility of a field absorption type device is provided to measure easily an optical variable by using an optical current. CONSTITUTION: A lens type fiber(21) transfers a laser beam emitted from a variable wavelength laser(10). The laser beam passing through the lens type filter(21) is irradiated on a section of a device(15). A chopper(11) turns on or off the variable wavelength laser(10). An optical rotator(14) is formed at a position adjacent to a polarization controller(13) in order to control a path of the laser beam. An optical detector(16) is connected with the optical rotator(14) in order to measure a change of reflective intensity of a reflected beam. A lock-in amplifier(17) is connected with the chopper(11) in order to detect a modulated variable wavelength laser beam. A power supply(18) supplies power to each component. A voltage separator(18) separates a signal influence between the device(15) and the lock-in amplifier(17).
