“…The fabrication processes of the laser involve two-step liquid-phase epitaxy (LPE) growth which has been described in great detail in the literature [6]. The only difference is the growth of two active layers by the "threemelt technique" [5].…”

Abstract-A buried crescent InGaAsP-InP laser with two active layers was fabricated to study the temperature behavior of the doublecarrier-confinement structure. An anomalously high-characteristic temperature To was measured and an optical switching behavior was observed. A model analysis and numerical calculation using a rate equation approach explained qualitatively very well the experimental results. It was revealed that not only the Auger recombination in this special double-active-layer configuration, but that the temperature dependent leakage current, which leads to uniform carrier distribution in both active regions, is essential to increase To.

“…To get rid of the degradation, a new "displaced" buried crescent (D BC) laser structure in which the p-n junction is displaced from the exposed surface by means of Zn diffusions from P-InP blocking layer to the n-lnP cladding layer during and after the second growth was proposed by Hirano et at (1983). The lasing characteristics of the BC lasers are obviously improved (Oomura et al 1984) to make InGaAsP/InP lasers a suitable light source for optical fibre communications.…”
