Universal lineshapes at the crossover between weak and strong critical coupling in Fano-resonant coupled oscillators
Simone Zanotto, Alessandro Tredicucci
In this article we discuss a model describing key features concerning the lineshapes and the coherent absorption conditions in Fano-resonant dissipative coupled oscillators. The mo…
Vertical coupling of laser glass microspheres to buried silicon nitride ellipses and waveguides
Daniel Navarro-Urrios, Joan Manel Ramirez, Nestor E. Capuj +3
We demonstrate the integration of Nd3+ doped Barium-Titanium-Silicate microsphere lasers with a Silicon Nitride photonic platform. Devices with two different geometrical configurat…
Far-field characterization of the thermal dynamics in lasing microspheres
J. M. Ramirez, D. Navarro-Urrios, N. E. Capuj +4
This work reports the dynamical thermal behavior of lasing microspheres placed on a dielectric substrate while they are homogeneously heated-up by the top-pump laser used to excite…
