The sample consisted of an InGaAs well, GaAs barriers, and graded AlGaAs cladding layers. It lased at 974 nm. The electro-luminescence shows a peak near 970 nm in the TE mode and a peak near 940 nm in the TM mode.application/pdf153018 bytesapplication/pdfen-US[SDGs]SDG7journal article10.1109/LEOS.1995.484895http://ntur.lib.ntu.edu.tw/bitstream/246246/2007041910032102/1/00484895.pdf
