The Fan Lab at Stanford University has developed an ultra-fast, physics-augmented, deep learning enhanced surrogate field solver for high-speed electromagnetic simulation and optimization. Denoising WaveY-Net uses a two-stage approach to target different field error sources.
Active manipulation of light beams is required for a range of emerging optical technologies, including sensing, optical computing, virtual/augmented reality, dynamic holography, and computational imaging.
Stanford researchers in the Vuckovic group have developed an optical phased array (OPA) for solid-state beam-steering in optical systems such as LIDAR, projectors, and microscopy.
Researchers at Stanford have developed an ultracompact, high-quality-factor (high-Q) metasurface that enables more convenient phase contrast imaging. Phase contrast imaging is a critical technique in biology and medicine to image essentially transparent objects such as cells.
Stanford researchers in the Fan Lab have developed a method that dramatically accelerates and optimizes metamaterial design with little computational resource and time using generative neural networks.
Stanford researchers in the Fan Lab have developed a photonic device optimizer that generates designs with hard geometric constraints to guarantee device fabricability.
High quality factor ("high-Q") photonic technology has revolutionized information processing, communications, sensing and nonlinear optics. Researchers in the Dionne Group at Stanford have developed a scheme to generate, for the first time, high-Q phase gradient metasurfaces.
Stanford researchers developed a method to make large phase shifts with little or no power dissipation in integrated optics. The approach uses a directional coupler moved by a MEMS actuator to achieve a path delay, i.e. an effective change in refractive index.
Stanford researchers have developed an optical coating that steers infrared and visual light in different paths while suppressing the typical undesired rainbow effect.
Stanford researchers at the Vuckovic Lab have created a computational nanophotonic design library for gradient-based optimization called the Stanford Photonic INverse design Software (Spins).
Stanford researchers have patented a silicon germanium (SiGe) electroabsorption modulator that can operate well in excess of 10 Gbps and is entirely compatible with Silicon (Si) complementary metal-oxide semiconductor (CMOS) integrated circuit fabrication.
