2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama).
We present on-chip detection from directly modulated microring quantum-dot (QD) lasers grown on exact (001) Si. Static and dynamic properties of the QD-based microring lasers and microdetectors have been investigated. The ring lasers exhibit high tem

2018 IEEE 15th International Conference on Group IV Photonics (GFP).
We present recent progress in performance and reliability of InAs quantum dot lasers epitaxially grown on (001) on-axis silicon. Fabry-Perot lasers show low threshold current densities ( 185 mW) and extrapolated lifetimes more than 10 million hours.

Quantum dot lasers are excellent on-chip light sources, offering high defect tolerance, low threshold, low temperature variation, and high feedback insensitivity. Yet a monolithic integration technique combining epitaxial quantum dot lasers with pass

We analyze the structure of dislocations in electrically aged InAs quantum dot (QD) lasers on silicon to understand gradual device degradation. We find that misfit dislocations lengthen due to carrier injection, experiencing a combination of recombin

Superlattice structures of In(Al)GaAs with localized ErAs trap centers feature excellent material properties for terahertz (THz) generation and detection. The carrier lifetime of these materials as emitter and receiver has been measured as 1.76 ps an
