Very high power DFB CW light source at 1550 nm for high-performance supertrunking

摘要

High power DFB laser emitting at 1550 nm wavelength is one of the key components for broadband supertrunk transmission systems. A CW optical power of 108 mW coupled into a polarization maintaining fiber was demonstrated from a high power InGaAsP/InP multi-quantum well DFB laser at 1550 nm wavelength. The laser also displays excellent high temperature performance, low noise, and narrow linewidth.
