Bound states in the continuum(BICs)can confine light with a theoretically infinite Q factor.However,in practical on-chip resonators,scattering loss caused by inevitable fabrication imperfection leads to finite Q facto...
Bound states in the continuum are realized in many optical systems as“dark states”,and their presence can be detected in the regime of leaky modes via resonances in far-fields.Here the authors reveal previously unse...
The extreme spectral broadening of light in supercontinuum generation(SCG)is considered by many as the ultimate legacy of nonlinear optics.In this interview,Light:Science&Applications invited John Dudley[see the“Shor...
