N2 - We show theoretically that Fabry-Perot semiconductor lasers using narrow asymmetric waveguides can offer much higher temperature stability of the lasing wavelength compared to structures with standard symmetrical waveguides. The mechanism of the low thermal sensitivity is the uniquely strong wavelength dependence of the confinement factor near the waveguide cutoff, which increases the blueshift of the modal gain peak with carrier density and helps offset the bandgap shrinkage with temperature.
