Widely tunable cavity-enhanced backward difference-frequency generation
Ming-Yuan Gao, Yue-Wei Song, Ren-Hui Chen +3
Difference-frequency generation (DFG) is a powerful technique for generating widely tunable infrared radiation. However, conventional phase-matching schemes may require tuning mult…
Observation of tuning properties in a doubly resonant backward optical parametric oscillator
Ming-Yuan Gao, Yue-Wei Song, Zhi-Cheng Guo +3
Doubly resonant optical parametric oscillators (OPOs) under continuous wave (CW) pumping are particularly notable for their low threshold and narrow linewidth. Backward OPOs (BOPOs…
Cavity-enhanced symmetric second-harmonic generation
Ming-Yuan Gao, Zhi-Yuan Zhou, Bao-Sen Shi
As one of the two types of backward second-harmonic generation (SHG), symmetric SHG exhibits some physical characteristics and application prospects that are distinct from those of…
Generation of Near-ideal Indistinguishable Two-Photon State by Incoherent Light
Yue-Wei Song, Ming-Yuan Gao, Zhi-Cheng Guo +5
High-quality quantum states lie at the heart of advanced quantum information processing. The degree of photon indistinguishability is critical for applications from photonic quantu…
