Abstract:
InGaAs/InGaAlAs laser diodes operating in the 1.55-$\mu$m spectral range are studied. It is demonstrated that a certain level of carbon doping (10$^{12}$ cm$^{-2}$ per a single quantum well) allows one to reduce the temperature coefficient of variation of the lasing wavelength in such structures and raise the characteristic temperature of threshold current and differential efficiency at temperatures from 16 to $\sim$50$^\circ$C. These changes are accompanied by an increase in threshold current density and a reduction in differential efficiency.
Keywords:
semiconductor laser, quantum well, characteristic temperature, modulation doping.
