High-$Q$ Single-Layer Dimerized Nanometallic Grating for Free-Space Optical Modulator
High-speed free-space modulator with <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q$</tex>-tuned single-layer dimerized nanometallic grating using organic electro-optic material is demonstrated. Stable resonance across 100-nm wavelength range and efficient intensity modulation with a record-high <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$Q$</tex> factor of 470 are achieved experimentally.
