Engineering localised modes via drive and dissipation in photonic lattices

Alberto Amo

Laboratoire de Physique des Lasers, Atomes et Molécules, University of Lille - CNRS, France

The engineering of localised modes in photonic structures is one of the main targets of modern photonics. An efficient strategy to design these modes is to use the interplay of constructive and destructive interference in periodic photonic lattices. This mechanism is at the origin of defect modes in photonic bandgaps, bound states in the continuum and compact localised states in flat bands. In this presentation we show that in lattices of lossy resonators, the addition of external optical drives with controlled phase enlarges the possibilities of manipulating interference effects and allows designing novel types of localised modes [1]. We show that light can be localised down to a single site of a photonic lattice in a fully reconfigurable manner. We use the technique to engineer dissipative solitons in topological gaps [2]

Pulse self-compression down to the sub-cycle regime in hollow capillary fibers with decreasing pressure gradients

Marina Fernández Galán, Enrique Conejero Jarque, Julio San Roman

Universidad de Salamanca, Spain

We theoretically demonstrate an enhancement in the generation of clean, near-infrared sub-cycle laser pulses by soliton self-compression in gas-filled hollow capillary fibers using decreasing pressure gradients. Furthermore, we identify the optimal input parameters for high quality compression and the main advantages of this promising technique which paves the way towards ultrafast vacuum experiments.

We identify, via numerical simulations, the regime of enhanced frequency chirp during nonlinear propagation in multipass cell. This regime - used before the dawn of chirped pulse amplification to generate ultrashort pulses - paves the way for the generation of temporally clean fewcycle pulses. Here, we demonstrate numerically that the spectra of pulses from an Yb-based laser system can be broadened into a flat supercontinuum with a smooth spectral phase compatible with a clean few-cycle pulse with temporal secondary structures with peak intensity below 0.5% that of the main peak.
