ABSTRACT
The polarization dependence of the gain/current relation and threshold current of quasi-index-guided laser diodes is analyzed for the case of λ=1.3 μm InGaAsP-InP ridge-waveguide lasers. Thereby it is shown that three different regimes for the stripe width and the lateral effective index discontinuity can be distinguished where one modal polarization (TE or TM) predominates. The significance of this finding on laser design and polarization control is discussed, and a comparison is performed on experimental results.
