Abstract

We report development of SLD emitters with reduced dependence of SLD power on ambient temperature, and study of their performance parameters over very wide temperature range. SLDs were able to deliver up to 0.1 mW output power from SM fiber till +100 degC ambient temperature. Wavelength dependence on operation temperature was measured within range from -55 to +85 degC with the help of hermetic fiber pigtailed modules on the base of such SLDs. Parameters governing power stability of such modules are discussed. It is shown that SLD wavelength dependence on temperature may be linearly approximated with relative tolerance of less than 3 X 10^-3, second-order approximation by parabola results in less than 3 X 10^-4 relative mistake. It is found that experimental coefficients in wavelength-on- temperature approximations are close to fundamental bandgap wavelength dependency of AlGaAs.
