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.
Researchers at Stanford have developed a dielectric diffraction grating that provides high (near-unity) diffraction efficiencies in an ultra-compact volume.
Researchers at Stanford have developed methods for evaluating the position of a micro-electromechanical system (MEMS) device in terms of phase and/or amplitude characteristics.
Stanford researchers at the Prakash Lab have developed Octopi, a low-cost ($250-$500) and reconfigurable autonomous microscopy platform capable of automated slide scanning and correlated bright-field and fluorescence imaging.
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 Kasevich Lab have prototyped a multi-pass electron microscope that can image nanometer scale samples including electron damage sensitive proteins and other electron dose sensitive nanostructures with low damage.
Stanford researchers have invented a C-Aperture Nano-Tip which provides a new way to further enhance the optical resolution down to smaller than 15 nm.
Stanford researchers successfully manufactured high quality optical components using commercially available 3D printing. The 3D printed optics were easy to fabricate and inexpensive.
Stanford researchers patented a method to design, computationally optimize and fabricate efficient optical devices using semiconducting and dielectric nanostructures.
An interdisciplinary team of Stanford researchers is developing a dual axis confocal (“DAC”) microscope system for in vivo imaging of tissues at the cellular scale.
Researchers at the Solgaard Lab have demonstrated that light sheet fluorescence microscopy (LSFM) with structured and pivoting illumination enables fast image acquisition and improved image quality.
Precision in surgical removal of cancer is guided by pathological assessment of resected tissues, and there is a dire need to reduce the time and distance between the critical diagnostic events and the surgical procedure.
