Improved Temperature Dependences of GaInAsP/InP DFB Lasers with Wirelike Active Regions by Bragg Wavelength Detuning
By adopting Bragg wavelength detuning into DFB lasers with wirelike active regions, the changes of threshold current densities and differential quantum efficiencies as low as plusmn19% and 24%, respectively, were obtained between 10degC and 85degC.
