The QLF133x, QLF131x, QLD133x and QLD131x Quantum dot lasers are 1300 nm semiconductor lasers grown on GaAs substrates based on quantum dot technology. Some QDLasers Quantum dot laser have been designed to operate at extremely high temperatures (e.g.150-200C) and can be used in harsh-environment applications. Their excellent stability at high temperatures and excellent optical feedback tolerance makes them also ideal light sources for silicon photonics.
