摘要： Disclosed wideband optical fiber amplifier amplifies and outputs wideband optical signal containing C-band and L-band optical signals. The amplifier includes: a first amplification section amplifying the wideband optical signals; a second amplification section amplifying the separated L-band optical signals amplified by the first amplification section; an optical signal coupler combining and outputting the optical signals amplified by the first and second amplification sections; and an optical circulator. A first port of the optical circulator inputs the wideband optical signals from the optical communication network; a second port outputs the inputted wideband optical signals and inputs spontaneous emissions generated from the first amplification section; a third port provides the spontaneous emissions to the second amplification section while inputting the L-band optical signals amplified by the second amplification section; and a fourth port outputs L-band optical signals that were inputted to the third port to the optical signal coupler.

摘要： A method and apparatus for estimating the contour of a user object in a moving picture during video communications so that a personal background image is not provided during video communications. Information about center coordinates as well as a size of a face of the user object is extracted from a moving picture frame. Edges are extracted from the moving picture frame, and a boundary of a head of the user object is estimated using a semicircle. The boundaries of left and right shoulders and left and right arms of the user object are estimated using second-order function graphs that overlap a largest portion of the edges. An entire contour of the user object is estimated according to the boundaries of the head, the left and right shoulders, and the left and right arms of the user object.

The multiplexer includes a forward arrayed waveguide grating for demultiplexing the respective channels of the forward optical signal inputted thereto, for adding or dropping a channel to the demultiplexed channels of the forward optical signal, and for multiplexing the channel-added or dropped channels; a reverse arrayed waveguide grating for demultiplexing respective channels of the reverse optical signal inputted thereto, for adding or dropping a channel to the demultiplexed channels of the reverse optical signal, and for multiplexing the channel-added or dropped channels; a first circulator for inputting the forward optical signal to the forward waveguide grating and outputting the reverse optical signal received from the reverse waveguide grating to one of the waveguides, and, a second circulator for inputting the reverse optical signal to the forward waveguide grating and outputting the forward optical signal received from the forward waveguide grating to the other waveguide. Using this arrangement, the bidirectional add/drop multiplexer is capable of cutting off the relative intensity noise while avoiding the collision of the forward and reverse optical signals.
