F. Vermaerke et al., SIMPLE RELIABLE PROCESSING TECHNIQUE FOR LOW-THRESHOLD HIGH-POWER STRAINED INGAAS-ALGAAS GRINSCH SQW LASER-DIODES, IEE proceedings. Part J, Optoelectronics, 140(1), 1993, pp. 75-79
A simple and highly reliable processing technique for ridge waveguide
InGaAs/GaAs SQW lasers is proposed. Comparison is made with other more
conventional processing sequences and measurements show that the char
acteristics of the lasers obtained by this simple method are at least
as good as and sometimes better than those made by the other processin
g sequences. It is shown that the simplicity of the process guarantees
a high yield. The high performances of these lasers are further optim
ised by the application of optical coatings.
