Title: Widely tunable and narrow-linewidth chip-scale lasers from near-ultraviolet to near-infrared wavelengths

Authors: Mateus Corato-Zanarella, Andres Gil-Molina, Xingchen Ji, Min Chul Shin, Aseema Mohanty, Michal Lipson (all from the Department of Electrical Engineering, Columbia Engineering; Ji now at John Hopcroft Center for Computer Science, Shanghai Jiao Tong University; Shin a research scientist at Reality Labs, Meta;  Mohanty at Department of Electrical and Computer Engineering, Tufts University)

Funding: This work was supported as part of the Novel Chip-Based Nonlinear Photonic Sources from the Visible to Mid-Infrared funded by the Army Research Office (ARO) under award no. W911NF2110286. The photonic chips fabrication was done in part at the City University of New York Advanced Science Research Center NanoFabrication Facility, in part at the Columbia Nano Initiative (CNI) Shared Lab Facilities at Columbia University, and in part at the Cornell NanoScale Facility, a member of the National Nanotechnology Coordinated Infrastructure (NNCI), which is supported by the National Science Foundation (Grant NNCI-2025233). M.C.S. is supported by the Facebook Fellowship Award.

COI: M.C.Z., A.G.M, X.J., M.C.S., A.M., and M.L. are named inventors on US provisional patent application 63/275,141 regarding the technology reported in this article.
