Description
We develop a perturbation theory for slow-light photonic-crystal waveguides engineered to suppress group-velocity dispersion, and predict that weak material loss (gain) is enhanced proportionally to the slow-down factor, whereas the attenuation (amplification) rate saturates for loss (gain) exceeding a certain threshold. This happens due to hybridization of propagating and evanescent modes which allows significant intensity enhancement observed in our numerical simulations for photonic crystal...[Show more]
