概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)
This work demonstrates UV microlaser based on bound states in the continuum (BICs). Designed sub-wavelength dielectric photonic crystal support BIC and achieve strong light confinement in the gain.
実験 / Experimental
The experimental session includes: 1. Patterning of dielectric sub-micrometer periodic structure with electron-beam lithography. 2. Characterizing fabricated samples with scanning electron microscope
結果と考察 / Results and Discussion
The fabricated ZEP520A line-and-space periodic structure is proved to support optical BIC and corresponding narrow-width UV lasing. Additionally, structures with varied periods (0.5 nm/step) were fabricated and characterized to prove that the control of lasing wavelength is achievable.
