Wide range of operating conditions for a 1000 km-2.5 Gb/s transmission with a new WDM optimized design of integrated laser-electroabsorption modulator

A new wavelength-division multiplexed (WDM) optimized design of integrated electroabsorption modulator distributed feedback lasers provides a great tolerance on operating conditions and laser wavelength: 2.5 gbit/s transmission over 1000 km is performed for /spl Delta/I/sub laser/=70 mA, /spl Delta/T/sub chip/=20/spl deg/C, and /spl Delta//spl lambda//sub laser/=10 nm.
