Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films
Advanced Science, EarlyView.The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.

A systematic analysis of parametric instabilities in nonlinear parabolic multimode fibers
APL Photonics, 2019 We provide a systematic analysis of geometric parametric instabilities in nonlinear graded-index multimode fibers. Our approach implicitly accounts for self-focusing effects and considers dispersion processes to all orders. It is shown that the resulting

CW‐Pumped Amplified Spontaneous Emission From Thermally Evaporated CsPbBr3 Films
Advanced Science, EarlyView.Thermally evaporated CsPbBr3 thin films sustain amplified spontaneous emission from short‐pulse toward quasi‐continuous‐wave excitation. Time‐resolved spectroscopy, controlled excitation, and substrate engineering reveal how excitation duration governs optical‐gain stability.
