WDM Nanoscale Laser Diodes for Si Photonic Interconnects
Abstract
The goal of this work has been to develop nanoscale VCSELs for integration into various optical systems, including for mounting on silicon. The nanoscale VCSELs can achieve small optical modes and present a compact laser diode that is also robust. In this work we have used a lithographic design and fabrication to realize a new type of VCSEL that is oxide free. Lithographic VCSELs as small as 1 m diameter have been developed that deliver high power and low threshold. Slightly larger VCSELs of 2 m size produce high efficiency, reaching 50 % power conversion efficiency. Stress testing has shown that the new VCSEL can produce reliability that exceeds commercial oxide VCSELs.
