Title: Method and apparatus for an optical fiber amplifier
Inventor: FIDRIC BERNARD G
IPC: H01S3/067
Filed: 1998-01-12
Granted: 2000-04-21
Abstract: An amplifier method and apparatus for use with optic systems utilizing a fiber optic circulator to direct input signals to a splitter that splits the copropagating pump light and input signals into two equal parts for simultaneous introduction into the two opposite ends of the active gain fiber. Half of the pump light and half of the signal are propagating through the active fiber in a clockwise and counterclockwise direction at the same time. This bidirectional propagation results in more uniform excitation along the entire length of the active fiber, providing uniform stimulation of photon emission at both ends, causing significantly reduced noise and higher gain of the signal. Two half-amplified  signals are combined and supplied to the circulator that provides the amplified output signal without any residual pumping light at the input or the output port of the circulator.

A stage counter directs changes of mode, for wirting data to the memory or reading data from the memory. The address counter designates an address of the memory by sequentially increasing or decreasing the address number, and a comparator compares the input data DRIN output by the BIST information signal generator to the memory with an output data DROUT output from the memory, to generate a fail indication signal ERR indicating whether or not the memory has failure. The clock counter 219 counts the number of clock cycles until the error of the memory occurs, and a clock register stores the number of clock cycles counted by the clock counter. A refresh counter counts the number of refreshes of the memory while communicating with the BIST information signal generator.
