Vertical-Cavity Surface-Emitting Laser With a Chiral Nematic Liquid Crystal Overlay
IEEE Photonics Journal, 2014 We demonstrate measurement results of the light emission of vertical-cavity surface-emitting lasers (VCSELs) with chiral liquid crystal (CLC) overlay (CLC-VCSEL). Two different CLC materials with different chiral-phase temperature range are presented and

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 ...

Spin Laser Local Oscillators for Homodyne Detection in Coherent Optical Communications
Micromachines, 2021 We numerically investigate spin-controlled vertical-cavity surface-emitting lasers (spin-VCSELs) for local oscillators, which are based on an injection locking technique used in coherent optical communications.
