摘要

只提供摘要形式。综上所述，采用改进的p镜设计和AlAs湿氧化技术，实现了低阈值(420 /spl mu/A)、宽波长跨度(44.8nm)的InGaAs DBR QW VCSEL阵列。通过器件尺寸的控制和低压p-DBR激光器的低散热，在20.8nm的跨度内实现了单模工作。

Low-threshold multiple-wavelength vertical-cavity laser arrays with single-mode operation

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.
