CMOS Compatible Add-drop Silicon-Organic Hybrid Racetrack Modulator

Optical modulators are vital in various applications, including data transmission, optical computing, and sensing. Current optical modulators rely on silicon due to compatibility with complementary metal-oxide semiconductor (CMOS). However, silicon modulators face challenges in terms of speed, energy efficiency, and area. This necessitates adding new materials to silicon platforms. Here, we design and fabricate a CMOS-compatible add-drop silicon-organic-hybrid racetrack modulator. It promises a high modulation bandwidth(96GHz) and low energy consumption(0.16fJ/bit), enabling the next generation of optical computing and data transmission.
