155 Mbit/s transmission using ASE-injected Fabry-Perot laser diode in WDM-PON over 70°C temperature range

Abstract

Thermal reliability of an uncooled Fabry-Perot laser diode (F-PLD) wavelength-locked to spectrum-sliced amplified spontaneous emission (ASE) as a source for wavelength division multiplexed-passive optical networks (WDM-PONs) is presented. An F-PLD with narrow mode spacing and asymmetric facet reflectivity relieved temperature dependency of transmission and power requirement of ASE injection. The chip temperature range of error-free transmission at 155 Mbit/s extended over 70°C with −22 dBm ASE injection.
