We report a nano-electromechanical optoelectronic (NEMO) tunable VCSEL with a record compact (140 nm times3 mum times3 mum) TE-polarized high contrast grating (HCG). A record high tuning speed of ~60 ns is experimentally demonstrated with single mode operation (SMSR ~ 40 dB).
We present a nano-electromechanical optoelectronic tunable VCSEL utilizing a mobile and super-thin single-layer high-index-contrast subwavelength grating. Ultra-low threshold and single mode emission laser with continuous wavelength tuning range ~18 nm and ultra-fast tuning speed ~150 ns was experimentally obtained.
