    摘要： A light-controlled light modulator can achieve high-speed, low-loss wavelength conversion. Continuous light with a wavelength &lgr;j is launched into an MMI coupler via a port, and is split into two parts by the MMI coupler, which are led to a loop-type interferometer. In the loop-type interferometer, the two parts travel separately around the loop as clockwise traveling light and counterclockwise traveling light, are combined by the MMI coupler again via a filter-equipped phase modulator, thereby being emitted to the port. In this state, signal light &lgr;i(s) with a wavelength &lgr;i is launched into the filter-equipped phase modulator via a port. Even when the wavelength &lgr;i of the signal light &lgr;i(s) is equal to the wavelength &lgr;j of the wavelength converted output light, the wavelength conversion can be achieved with preventing noise from being mixed into the output light emitted from a port.

    摘要： An optical communication equipment comprises shared optical sources 88a–88d to be shared by communication nodes 100a–100d, the wavelengths of optical signals 76a–76d are converted into desired wavelengths λa–λd according to the addressed information of the corresponding optical label signals 77a–77d by using the shared optical sources 88a–88d, and routed to the addressed communication nodes without being converted into electrical signals by using the wavelength routing function of the cyclic-wavelength arrayed-waveguide grating (AWG) 120. The load of each communication node can be reduced by incorporating the multi-wavelength optical sources, which can be shared among individual communication nodes, into the router 80. Further, each communication node is provided with an optical gate or the like for returning the optical signal to the communication node from which the optical signal has been transmitted through the router 80 in order to adjust the transmission time lag between the optical signal and the corresponding optical label signal by the controllers 110a–110d.

    摘要： The present invention provides a double-cylinder type apparatus for the regeneration of active carbon, which comprises a heating furnace provided with at least one burner and at least one annular regeneration chamber composed of at least one set of an inner cylinder and an outer cylinder installed concentrically inside said heating furnace, said outer cylinder having a plurality of holes penetrating the side wall thereof, wherein the spent active carbon is supplied to the upper part of said annular regeneration chamber and the regenerated carbon is to be taken out at the lower part of the same. The heating of said annular regeneration chamber from the side of said inner cylinder is performed either by introducing the flue gas arising in said heating furnace into the inner cylinder or by providing at least one burner within said inner cylinder and utilizing the combustion gas from said burner. The spent active carbon can be regenerated by subjecting the same to the process comprising drying, calcination and reactivation by the use of the flue gas.
