Laser-Direct-Written polymer WGM microring laser integrated on a fiber tip for refractive index sensing
Mobin Yaghoobi, Seyedeh Mahshad Hosseini, Leila Hajshahvaladi +2
Whispering-gallery-mode (WGM) microlasers are promising for refractometric sensing, but their practical implementation can be limited by the need for stable resonator-coupler align…

BIC-Engineered Silicon Nitride Microring Resonators Enabled by an Etch-Free Laser-Writing Approach
Leila Hajshahvaladi, Mohammad Amin Salmani, Media Abbasi +3
We report the initial experimental demonstration of a complementary, etch-free approach with fewer fabrication steps, in useful SU-8 ridges written by direct ultraviolet laser lith…
