大功率垂直腔面发射激光器列阵的串接结构
High-power vertical cavity surface emitting laser array in series structure
摘要
Abstract
For increasing the output powers without improving drive currents to high power VerticalCavity Surface Emitting Lasers(VCSELs),a VCSEL in series structure was presented.First,theVCSEL chips were soldered on a A1N ceramic heat sink,then the chips were connected by a wirebonding in series.The output powers of four-chip devices in series,tWO-chip devices in series and asingle device were measured under microsecond and nanosecond pulses,which are 775,416,217 mWand 18.9,9.8,5 W,respectively.Test results show that the output powers of the first tWO kinds ofdevices in series are about 4 times and twice that of the single device.Moreover.The Full Width atHalf Maximum(FWHM)of multiple-chip devices in series is slightly wider than that of the single device,which can be improved by choosing good uniformity cascade chips.In conclusion,the VCSEL inseries structure can increase the output power without improving the drive current.关键词
