Abstract :
A burst-mode APD-ROSA using a reset signal with a very short response time to a burst-mode optical input signal ( λ = ~1300 nm, modulation formats of on-off-keying) for a 10G-EPON and GE-PON dual-rate system was developed. We analytically investigated the relationship between the response time and the multiplication characteristics of an APD to reduce the response time. From the calculation results, we determined a suitable resistance for a bias circuit that enabled us to obtain three key characteristics of burst-mode receiver performance, namely high sensitivity, wide dynamic range and short response time. We fabricated an APD-ROSA based on the calculation results, and demonstrated burst-mode receiver operation with a fast response of about 80 ns but without degrading the sensitivity or distorting the waveform.
