Title: Loss tilt equalizer
Inventor: MOBARA MASAICHI
IPC: H04B10/294
Filed: 2002-10-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a loss tilt equalizer in which a loss is substantially linear to a wavelength and the loss tilt is variable.  <P>SOLUTION: The light entering an input port 101 of the equalizer 100 takes loss based on a wavelength when passing a variable filter 110 and fixed filter 120, respectively, and made to output from an output edge 102. When the transmission spectrum of the variable filter 110 is in either state within a variable range, an overall loss spectrum of the equalizer 100 is substantially flat resulting from that each loss spectrum of the variable filter 110 and fixed filter 120 has reverse characteristics with each other. The transmission spectrum of fiber grating included in the variable filter 110 is varied by the temperature regulation using a Peltier element 130, so that the overall loss spectrum of the equalizer 100 varies in the loss tilt while the loss is substantially linear to the wavelength.  <P>COPYRIGHT: (C)2004,JPO
