Fast switching gigabit/s CMOS burst-mode transmitter for PON applications

摘要

A burst-mode transmitter with automatic power control which is capable of waveform shaping, fast laser on/off switching, and driving over 60mA modulation current is presented in this paper. It is constructed by a driver which was fabricated in 0.25/spl mu/m 1P5M CMOS process with a 2.5-Gb/s 1310nm-wavelength Fabry-Perot laser diode. Measurements show clear eye diagrams operating over 2.5-Gb/s data rate with 84/97ps rise/fall times. The turn on/off delay of modulation current is less than 6ns. And the laser turn on/off time is about 30/20ns which is applicable for EPON or even GPON applications.
