Ultra-broadband supercontinuum generation in gas-filled photonic-crystal fibers: the epsilon-near-zero regime

Supercontinuum generation in bulk and photonic crystal fibers

In this paper we overview the concept of supercontinuum generation (SCG) and take a brief look at several mechanisms that are believed to give rise to this not yet fully understood phenomenon. We will emphasize why photonic crystal fiber (PCF) is a more desirable medium for observation of SCG and will conclude with a discussion of several emerging applications.

Soliton-radiation trapping in gas-filled photonic crystal fibers

Broadband Epsilon-Near-Zero Perfect Absorption in the Near-Infrared

Perfect absorption (PA) of incident light is important for both fundamental light-matter interaction studies and practical device applications. PA studies so far have mainly used resonant nanostructures that require delicate structural patterning. Here, we realize tunable and broadband PA in the near-infrared region using relatively simple thin film coatings. We adjust the growth condition of a...

Supercontinuum generation in photonic crystal fiber

A topical review of numerical and experimental studies of supercontinuum generation in photonic crystal fiber is presented over the full range of experimentally reported parameters, from the femtosecond to the continuous-wave regime. Results from numerical simulations are used to discuss the temporal and spectral characteristics of the supercontinuum, and to interpret the physics of the underly...
