43 Citations | However, chopping creates a ripple at the output of the amplifier, which is due to the upmodulated amplifier offset and flicker noise. |
Gain saturation is strong in any efficient amplifier and we show how it can be exploited to raise instability thresholds be a factor of two or more while staying below the stimulated Brillouin threshold. | |
Unlike solidly grounded systems, resistance- grounded systems are able to operate continuously with one unintentional ground. | |
07 Jun 1998 | Following this systematic design procedure we can improve the amplifier performance significantly. |

Another possibility is the use of a tapered amplifier, which is stabilized by a fiber bragg grating on the backside of the amplifier. | |
Coupled with adaption algorithms, the receiver can compensate for slow variations in power amplifier characteristics, where adjacent channel interference is created by power amplifier nonlinearities. | |
Furthermore, simulations tools can also be used to improve the tolerance of the fiber amplifier by helping identifying the best amplifier configuration for operation in the radiative environment. | |
Measurements demonstrate that the proposed amplifier achieves 45% noise power reduction in the amplification phase along with improved linearity and lower power consumption, when compared with the conventional amplifier. | |
Tuning of this amplifier is extremely simple. | |
