Abstract
In this paper, we proposed a new burst-mode optical transmitter structure which is suitable for high data rate operation such as Gb/s operation. With this structure we made a 1.25Gb/s burst-mode optical transmitter including a digitally controlled APC circuit for EPON systems using commercial 0.8m BiCMOS technology. It well functioned at 1.25Gb/s and showed good eye patterns with 53.3ps jitter, 191ps rise time and 258ps fall time. To characterize the APC function we measured optical output power as increasing external voltage VREF. The optical power is linearlyproportional to VREF at the rate of 0.293mW/V.
