1.3μm Optical Transmitter Module with Low Power Dissipation

A 1.3μm optical transmitter module with low power dissipation has been designed and fabricated. The structure feature, fabrication technology and characteristics of this module are described in this paper. It can be suitably used in single-wave or doublewave 34Mbit/s digital fiber transmission system. The power dissipation at output of the optical fiber is about -20dBm, the power dissipation is about 300mW, the modulation degree of the doublewave signals is 5～25%, and the optical pulse rise time is 3.5ns.
