Liquid-Crystal Spin-VCSEL with Electro-Optically Controllable Birefringence
Photonics, 2023 We suggest a new construction of spin-VCSEL with an embedded nematic liquid crystal (LC) in a second cavity. We design such a coupled-cavity LC-VCSEL and develop a procedure for calculating its LC-voltage dependent polarization resolved resonant ...

Wavelength-scale lithographic VCSELs
2021 27th International Semiconductor Laser Conference (ISLC), 2021 We demonstrated high-efficiency room-temperature lasing from lithographic-VCSELs (i.e., Li-VCSELs) with mesa diameters ranging from 0.75 to 2.0 mu m and emission wavelength tunability under continuous-wave optical pumping. The results represent a crucial step towards the realization of electrically pumped small size lasers.
