A new Microelectromechanical system (MEMS) grating modulator has been developed, offering significant advancements in optical efficiency and scalability for communication systems. By integrating a tunable sinusoidal grating with broadside-constrained continuous ribbons, a large-scale aperture of 30 脳 30 mm is achieved and supports high-speed modulation up to 250 kHz. The device achieves 90% optical efficiency and dynamic modulation contrast of over 95%掳 make it ideal for free-space optical communication and remote sensing. The dispersive properties of the device make it attractive in wavelength sensing applications including spectrometers and hyperspectral imaging systems. This innovation addresses critical challenges in aperture size, efficiency, and modulation speed, promising to enhance high-speed, energy-efficient communication networks.
