Bidirectional electrostatic MEMS-tunable VCSELs

|
By Kresten Yvind, Søren Hansen, Andrey Marchevsky, Arnhold Simonsen
| Optica
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.
