A. Kasukawa et al., STRUCTURAL DEPENDENCE OF 1.3-MU-M NARROW BEAM LASERS FABRICATED BY SELECTIVE MOCVD, Electronics Letters, 32(14), 1996, pp. 1304-1305
Lasing characteristics of 1.3 mu m narrow beam lasers have been invest
igated in terms of the energy separation between gain and waveguide re
gions simultaneously formed by selective MOCVD. The HR-coated lasers w
ith a large energy separation of 110meV exhibit a low threshold curren
t of 12mA, a high power of >50mW, and a high temperature of 120 degree
s C with narrow beam divergence of 11 degrees (horizontal) and 11 degr
ees(vertical).
