Abstract :
Monolithic 12 element 1.3 μm AlGaInAs-InP strained multi-quantum well laser arrays have been fabricated. The laser diodes on the array exhibit excellent uniformity with standard deviations of 0.008 mA, 0.011 W/A and 0.6 nm for threshold current, slope efficiency and lasing wavelength, respectively, at 20°C. In addition, a low crosstalk of -2.2 dB is achieved as other elements are simultaneously biased at 70 mA. A lifetime of >30 years is estimated for the lasers operating at 10 mW and 85°C
