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

Long Wavelength VCSEL-by-VCSEL Optical Injection Locking [PDF]
IEEE Transactions on Microwave Theory and Techniques, 2009 Vertical-cavity surface-emitting laser (VCSEL)-by-VCSEL optical injection locking to obtain high cutoff frequencies of 1.3-mum VCSELs is demonstrated. A detailed physical explanation of the underlying mechanism is presented. VCSELs from the same wafer have been used in a master-follower configuration.

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 ...
