    Abstract: A first semiconductor optical amplifier is disposed on a first arm of a Mach-Zehnder interferometer and a second semiconductor optical amplifier is disposed on a second arm. An optical splitter splits a probe light into two portions and applies one portion to the first arm and the other to the second arm. A first optical coupler combines the probe lights output from the first and second arms. A second optical splitter splits a data light into two portions. A second optical coupler applies one output from the second optical splitter to the first arm in the backward direction. A third optical coupler applies the other output from the second optical splitter to the second arm in the forward direction.

  • Patent number: 6828883
    Abstract: A reduced size ceramic block filter has trap holes whose center is askew from the line running through the center of the transmission poles such that the height-wise distance between its center and the center line of the transmission poles is greater than (dt+d1)/2, but not greater than 3/8 of the height of the filter. The trap hole is also width-wise spaced from the next nearest transmission hole by an amount which approximates the distance between transmission holes. Due to this layout the diameter of the trap holes are reduced in order to maintain performance which is equivalent to a conventional filter whose trap holes are timely aligned with its transmission poles. The combination of reduced trap hole diameter and reduced width-wise spacing between traps and transmission holes, results in a reduced size ceramic filter.
