On-chip OPO has tunable range extending from IR to green
Researchers at the National Institute of Standards and Technology (NIST; Gaithersburg, MD) and the University of Maryland (College Park, MD) have developed a silicon nitride (Si3N4) microchip-based optical parametric oscillator (OPO) that can produce light at wavelengths across much of the visible spectrum (red, orange, yellow, or green), in contrast to previous on-chip OPOs that […]
