J. Rennie et al., HIGH-TEMPERATURE (74-DEGREES-C) CW OPERATION OF 634 NM INGAALP LASER-DIODES UTILIZING A MULTIPLE-QUANTUM BARRIER, IEEE journal of quantum electronics, 29(6), 1993, pp. 1857-1862
A modified multiple quantum barrier structure has been applied to a 63
0 nm band laser diode. The result is a laser exhibiting a high maximum
operating temperature, of 74-degrees-C, and a low threshold current o
f 49 mA. These characteristics correspond to a 22-degrees-C increase i
n the operation temperature and over a 50% decrease in the threshold c
urrent, in comparison to an identical laser without a multiple quantum
barrier. This is the first time, to our knowledge, that a significant
decrease in the threshold current of a laser has been directly attrib
uted to the influence of a multiple quantum barrier.
