Optical amplifier noise figure measuring method and apparatus |
| abstract |
(57) [Abstract] [Purpose] Optical amplifier noise figure measurement method that allows easy, high-speed, and high-accuracy phase adjustment of the total system under test including the optical fiber that supplies the input signal to the measured optical amplifier. And a device. [Structure] An optical pulse signal C generated by modulating continuous laser light with a first pulse B having a period sufficiently shorter than the atomic lifetime of the upper energy level of a rare earth-doped optical fiber is applied to a measured optical amplifier 4. Input the measured optical amplifier 4 Of the output signal D of the first pulse B and Of the optical amplifier 4 to be measured based on the maximum optical power (PAMP + PASE) and the minimum optical power PASE of the optical signal H obtained by sequentially modulating the second pulse G whose phase difference increases with respect to the pulse B of Measure the noise figure. |
