Following on Jizhao’s post, I am very excited that this paper has been published in Nature Photonics! We show that in photonic-crystal resonators (PhCRs) microcombs can be 100% efficient with all the input light converted into useful comb light.?Microcomb laser sources are widely expected to be a critical element in high-capacity future systems, such as data centers, advanced AI and quantum computing architectures, and high-speed signaling. Strict efficiency in terms of power consumption is a singular metric in high-capacity systems to reduce electric and water consumption. PhCRs, patented by NIST, are exceptionally versatile, since they offer universal phase-matching for nonlinear optics. The research for this Nature Photonics paper was very interesting because it taught us that just like in quantum optics the fundamentals of microcombs only depend on the photon extraction rate from the device and the physics within. PhCRs and microcombs are critical innovations achieved by NIST researchers, performing on the DARPA PIPES program, AFOSR ultrafast science program, and NIST programs.
Thrilled to share our latest article published in Nature Photonics: https://lnkd.in/gqjHnjiS We demonstrate an approach to achieving near-unit conversion efficiency in microcombs. Special thanks to my colleagues at NIST Quantum & Nonlinear Nanophotonics Group and our PIPES team!
