A scheme for ultra-low noise avalanche multiplication of fiber optics signal.
01 January 1987
Current high speed device structures have carriers travelling across submicron device dimensions under the influence of extremely high electric fields. This gives rise to avalanche multiplication in a finite medium with only a few ionizing collisions per traversal of the primary carrier through the device. The finite medium avalanching results in a less uncertainty in the gain process and hence a promise for low noise avalanche multiplication.
