Stress engineering with silicon nitride stressors for Ge-on-Si lasers
Jiaxin Ke, Lukas Chrostowski, Guangrui Xia
Side and top silicon nitride stressors were proposed and shown to be effective ways to reduce the threshold current Ith and improve the wall-plug efficiency ηwp of Ge-on-Si lasers.…
Significant crosstalk reduction using all-dielectric CMOS-compatible metamaterials
Amin Khavasi, Lukas Chrostowski, Zeqin Lu +1
A recent computational result suggests that highly confined modes can be realized by all-dielectric metamaterials (S. Jahani et. al., Optica 1, 96 (2014)). This substantially decre…
Automatic Wavelength Tuning of Series-Coupled Vernier Racetrack Resonators on SOI
Hasitha Jayatilleka, Robert Boeck, Kyle Murray +4
Using in-resonator photoconductive heaters to both sense and control the intra-cavity light intensity of microring resonators, automatic tuning of a silicon-on-insulator two-ring V…
Monolithic Integration of AlGaAs Distributed Bragg Reflectors on Virtual Ge Substrates via Aspect Ratio Trapping
Yiheng Lin, Wei Shi, Jizhong Li +8
High quality AlxGa1-xAs distributed Bragg reflectors (DBRs) were successfully monolithically grown on on-axis Si (100) substrates via a Ge layer formed by aspect ratio trapping (AR…
