Abstract :
The design and implementation of a 5-Gb/s silicon bipolar laser driver IC for direct modulation of a laser diode is reported. The adjustable modulation current range is 15-45 mA. The IC can drive 25-Ω laser modules via a 25-Ω transmission line. Typical power dissipation is 930 mW for a modulation current of 45 mA. Though the IC has been fabricated on a production line instead of using a laboratory technology, it is one of the fastest laser driver ICs ever implemented in silicon. The ability to drive an ohmic load is shown, as well as the performance when driving a real laser module. The circuit has been successfully operated in a demonstrator system for digital optical-fiber transmission
