Current light sources lack tunability, require bulky external equipment or components, or only span narrow spectral ranges, limiting chip-scale photonic applications.</p>\r\r<h2>The Technology: Integrated chip-scale narrow-linewidth, broad-spectrum, highly tunable laser</h2>\r\r<p>This technology is a chip-scale laser that combines high-confinement silicon nitride resonators with commercially available Fabry-Perot laser diodes to create a platform that is tunable with narrow linewidth and broad spectrum. The silicon nitride resonators support low-loss light propagation throughout the visible and near-IR spectrum; additionally, the Fabry-Perot laser diodes provide tunability and a narrow linewidth. In combination, the platform offers a highly precise, broad-spectrum chip-scale laser, advancing chip-scale photonics.  </p>\r\r<h2>Applications:</h2>\r\r<ul>\r<li>Ion trapping</li>\r<li>Quantum photonics</li>\r<li>Biosensors</li>\r<li>Augmented and virtual reality devices </li>\r<li>Neural probes</li>\r<li>Nonlinear photonics </li>\r<li>Spectroscopy </li>\r</ul>\r\r<h2>Advantages:</h2>\r\r<ul>\r<li>Tunable</li>\r<li>Narrow linewidth </li>\r<li>Broad visible and near-infrared spectral coverage</li>\r<li>Compact, chip-scale design</li>\r<li>Low-loss light propagation </li>\r</ul>\r\r<h2>Lead Inventor:</h2>\r\r<p><a href=\"https://www.ee.columbia.edu/michal-lipson\">Michal Lipson, Ph.D.</a></p>\r\r<h2>Patent Information:</h2>\r\r<p>Patent Pending(US<a href=\"https://patents.google.com/patent/US20230288774A1/en?oq=US18%2f052%2c377\">20230288774</a>)</p>\r\r<h2>Related Publications:</h2>\r\r<p>*<a href=\"https://www.nature.com/articles/s41566-022-01120-w\">Corato-Zanarella M, Gil-Molina A, Ji X, Shin MC, Mohanty A, Lipson M. “Widely tunable and narrow-linewidth chip-scale lasers from near-ultraviolet to near-infrared wavelengths” Nat.
