Abstract

We investigate the performance of

$1.3~\mu $

m directly modulated multiple-quantum-well strained AlGaInAs distributed feedback laser in an optically amplified wavelength-division multiplexed (WDM) system for next-generation passive optical networks. We experimentally demonstrate

$2\times 53$

Gbit/s PAM-4 transmissions over 20 km of a single-mode fiber employing two 16-GHz bandwidth-limited directly-modulated lasers and compare the performance of quantum-well and quantum-dot semiconductor optical amplifiers (SOAs) in amplifying DWDM links. We successfully obtained the total power budget of 34 dB for each WDM channel using a quantum-dot SOA and 30-tap T-spaced feed-forward equalizer.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
