Singlemode lasers based on AlGaInAs/InAs/InP quantum-dash layers were for the first time fabricated with emission wavelengths in the 1.55 μm telecommunication band. A low thermal shift of the gain maximum in quantum-dash structures allows a wide operation temperature range for distributed feedback lasers.
