Abstract Visible light microlasers are essential building blocks for integrated photonics. However, achieving low-threshold (μW), continuous-wave (CW) visible lasing at room temperature (RT) has been a challenge because of the formidable requirement population inversion short wavelengths. Rare-earth (RE)-activated microcavities, featuring high-quality factor ( Q ) and small mode volume whispering gallery modes, offer great opportunity infrared-to-visible upconversion (UC) lasing. Here, we...
A compact, humidity-insensitive, fiber optic temperature sensor based on a quartz capillary, antiresonant reflecting optical waveguide was proposed and experimentally demonstrated. The transmission spectral responses of the were investigated regarding variation environmental humidity. Resonant dips exhibited sensitivity as large 201 pm/°C from -30 to 45 °C in humid environment. By coating sufficiently thick gold film onto surface, humidity cross-sensitivity issue effectively resolved. This...
We develop a hydrofluoric (HF) etching process to open microhole on the hollow glass microsphere (HGM). The typical whispering gallery mode (WGM) resonance was observed by coupling HGM with tapered fiber. Dioctyl phthalate filled into HGM, and wavelength decreased at elevated temperatures. analyzed WGM properties inside liquid-filled higher or lower refractive index in comparison wall. Four different liquids were also injected investigate influence of thermo-optic coefficient temperature...
This paper proposes a novel "micro-gun" structure for laser pulse propulsion. The "micro-bullets" (glass microspheres) are irradiated by with 10 ns duration in dynamic process. Experimental parameters such as the microsphere diameter and energy varied to investigate their influence on field spatial intensity distribution capillary tube were simulated using three-dimensional finite-difference time-domain method. experimental results demonstrate that propulsion efficiency is dependent size....
