Tunable fiber Fabry-Perot cavities with high passive stability
Optics Express, 2021 We present three high finesse tunable monolithic fiber Fabry-Perot cavities (FFPCs) with high passive mechanical stability. The fiber mirrors are fixed inside slotted glass ferrules, which guarantee an inherent alignment of the resonators. An attached piezoelectric element enables fast tuning of the FFPC resonance frequency over the entire free ...

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.
