Abstract

Single mode semiconductor lasers are widely used in spectroscopy, coherent optical communication, interferometry, holography. Their main parameters for these applications are output power, spectral linewidth, and side mode suppression. To ensure the single mode radiation, external and integrated spectral selective elements are often used. In recent years the high-efficient single mode laser diodes (LD) with the traditional cleaved cavity were created due to the utilization of quantum well (QW) structures.
