Bidirectional electrostatic MEMS-tunable VCSELs
Optics Letters, 2021 Microelectromechanical system (MEMS) vertical cavity surface-emitting lasers (VCSELs) are the fastest coherently tunable lasers (nm/ns) due to their unique Doppler-assisted tuning mechanism. However, in standard electrostatic actuation, the response is highly nonlinear and large (>100 V) dynamic voltages are needed for MHz sweep rates.

A buried tunnel junction 940 nm VCSEL for achieving thermal diffusion characteristics
AIP AdvancesTo investigate the performance degradation of a vertical-cavity surface-emitting laser (VCSEL) caused by self-heating effects, a 940 nm VCSEL with a buried tunnel junction (BTJ) and an aperture size of 10 μm was designed. The BTJ-type VCSEL achieves a 39.
