Abstract
Achieving good halftone reproduction in laser printing requires multi-level modulation of laser diodes. We proposed a hybrid modulation method that is basically pulse-width modulation (PWM) supplemented by intensity modulation (IM). This method is implemented as an IC, resulting in a small, high-speed LD controller module that can be mass produced at comparatively low cost.
