Claim Text:
1. A method comprising: receiving a set of optical pulses at an avalanche photodiode in linear mode or equivalent below-breakdown mode, each optical pulse having a beginning and an end; varying a reverse bias applied to the avalanche photodiode during the reception of each optical pulse at the avalanche photodiode, the reverse bias having a highest reverse bias level and a lowest reverse bias level during the reception of each optical pulse such that the highest reverse bias level is placed within a first half of each optical pulse received and the lowest reverse bias level is placed within a second half of each optical pulse eliminating impact ionizations in the avalanche photodiode near the end of each optical pulse received; and outputting from the avalanche photodiode an electrical signal that corresponds to the received optical pulse.
