A 156 Mbps CMOS laser diode driver for optical burst-mode transmission

Abstract

A 3.3 V, 156 Mbps laser diode (LD) driver with a mixed-signal feedback-type automatic optical power control (APC) has been devised for both a quick APC response of 1.5 /spl mu/s and the long holding time of optical power level between burst-data packets of more than 10-s for optical burst-mode transmissions. The LD driver is fabricated in standard triple-well 0.35-/spl mu/m CMOS technology, which can compensate for the degradation of LD optical power, moreover, any external adjustment of optical pulse width is unnecessary.
