Polarization Multiplexing Dammann Grating Based on All-Dielectric Metasurface
Published 2024-01-01Subjects: Get full textDammann gratings (DG) have become a powerful tool for generating multi-level spectral points in speckle arrays through binary phase variation. Conventional DGs are limited to regular dot arrays, such as squares and circular rings. Emergence of metasurface-based coding technology opens new ways for u...

Polarization Multiplexing Silicon-Photonic Optical Phased Array for 2D Wide-Angle Optical Beam Steering
Published 2021-01-01Subjects: Get full textWe propose the silicon photonic optical phased array (OPA) with large scanning angle by using polarization multiplexing. A Mach-Zehnder interferometer (MZI) switch together with a polarization splitter/rotator is utilized to select the polarization mode input to the OPA. By optimizing the...

Experimental demonstration of dual-polarization multiplexed optical phased array empowered by inverse design
Published 2025-06-01Subjects: Get full textThis paper presents a dual-polarization multiplexed optical phased array (OPA) implemented on a 220 nm silicon-on-insulator (SOI) platform, enabling continuous beam steering across TE and TM modes. While effectively guiding TE- and TM-polarized light, the proposed OPA on this platform faces the chal...
