1060nm single-mode metal aperture VCSEL array with transverse resonance for 5km single-mode fiber transmission

We demonstrate 5km-long single-mode fiber transmission using 1060nm single-mode intracavity-metal-aperture VCSEL array with over 46Gbps modulations. The metal-aperture causes transverse-resonance, resulting in single-mode operation and bandwidth enhancement. The effective bandwidth is improved thanks to the negative dispersion.
