Abstract

Extremely narrow spectral-linewidth characteristics in 1-5µm GaInAs/GaInAsP separate-confinement-heterostructure (SCH), quantum-well (QW), distributed-feedback, laser diodes (DFB LDs) are reported. Narrower linewidths were obtained in lasers with smaller numbers of quantum wells. Sub-MHz linewidth was achieved for the first time in single laser diodes.
