High-speed 850 nm VCSELs with 28 GHz modulation bandwidth for short reach communication
Paper i proceeding, 2013

We present results from our new generation of high performance 850 nm oxide confined vertical cavity surface-emitting lasers (VCSELs). With devices optimized for high-speed operation under direct modulation, we achieve record high 3dB modulation bandwidths of 28 GHz for similar to 4 mu m oxide aperture diameter VCSELs, and 27 GHz for devices with a similar to 7 mu m oxide aperture diameter. Combined with a high-speed photoreceiver, the similar to 7 mu m VCSEL enables error-free transmission at data rates up to 47 Gbit/s at room temperature, and up to 40 Gbit/s at 85 degrees C.
