Abstract :
Summary form only given. To summarize, multiple-wavelength InGaAs DBR QW VCSEL arrays with low threshold (420 /spl mu/A) and wide wavelength span (44.8nm) are achieved by using improved p-mirror design and AlAs wet oxidation. Through the device size control and less heat dissipation from the low-voltage p-DBR laser, single-mode operation is also obtained over a 20.8nm span.
