Abstract :
Various parameters in 1.55 ¿m buried-heterostructure DH laser design are obtained by simple analytical approximations and the effect of cavity length on laser characteristics. Threshold current density is found to vary strongly (3¿10 kA/cm2) with cavity length when cleaved short enough. Interference in far-field patterns is shown to depend on cavity length.
