[News] Voltage-Controlled Photonic Chip Could Make Smart-Glasses Displays More Efficient

Smart glasses need compact, efficient displays that can produce detailed images without drawing too much power. Laser beam scanning is one approach to meeting these requirements. Rather than using a fixed array of pixels, these displays steer a laser beam across the field of view, building an image point by point. Higher-resolution images can be produced without increasing the size of the optical components by switching colors more rapidly while using a fast-scanning mirror. Current systems, however, face limits in how quickly and efficiently they can control laser color. To prod...
