Abstract :
The authors present nano-electromechanical optoelectronic (NEMO) tunable VCSELs utilizing an ultra-thin, electrostatic-actuated single-layer (140 nm), high-contrast subwavelength grating designed to strongly reflect TE-polarized light. A 2 mW single-mode (SMSR ~45 dB) VCSEL with ultra-fast tuning speed ~90 ns is experimentally demonstrated.
