Reconstructive comb spectroscopy: A single-pixel detection paradigm beyond dual-comb limitations
Dongxu Zhu, Zhuoren Wan, Xiaoshuai Ma +13
Frequency comb spectroscopy has revolutionized broadband molecular fingerprinting with mode-defined resolution. While dual-comb spectroscopy stands as a dominant paradigm for high-…

Broadband terahertz comb with sub-Hz comb linewidth
Min Li, Yu Xia, Yuan Chen +6
Terahertz (THz) frequency combs are increasingly essential for spectroscopy, metrology, and quantum science. However, generating a dense array of evenly spaced ultra-narrow THz com…

Photo-Thermally Tunable Photon-Pair Generation in Dielectric Metasurfaces
Omer Can Karaman, Hua Li, Elif Nur Dayi +2
Photon-pair sources based on spontaneous four-wave mixing (SFWM) in integrated photonics are often spectrally static. We demonstrate and model a fundamental thermo-optical mechanis…
