Paper Abstract

Tunable lasers are becoming critical in DWDM systems for reasons of increased system functionality, system adaptability and costs. Key issues that arise are wavelength tuning range, characterization of the devices, wavelength control, mode stabilization, wavelength switching times, output power and long term stability of operation. We have developed tunable EML components and transmitters that address all these issues. Transmission at 2.5 Gb/sec over 640 km of fiber has been demonstrated using an EA-DBR capable of being tuned to any one of 20 wavelengths spaced at 50 GHz. These lasers are integrated into a single package with wavelength stabilization elements and can be stabilized such that both the desired wavelength and mode are maintained during operation. These integrated modules are also incorporated into a small form factor transmitter capable of operating in DWDM systems.
