Spectral and spatial filtering of whispering gallery modes in precision-engineered microbubble resonators
Ramgopal Madugani, Amal Jose, Christophe Pin +3
Similar to microspheres, thin-walled microbubble resonators support whispering gallery modes (WGMs) that combine ultrahigh Q-factors and small effective mode volumes. In contrast,…

Engineering Multi-wavelength Emission in All-Fiber Laser Mode-Locked Through Nonlinear Polarization Rotation
Subrata Manna, Amala Jose, K. Nithyanandan
The increasing demand for multi-wavelength optical sources to support dense wavelength-division multiplexing (DWDM) channels has driven the development of compact and reconfigurabl…
