Effect of loss on slow-light enhanced absorption in liquid-infiltrated photonic crystals

Abstract

We study slow-light enhancement of absorption measurements in photonic crystals composed of lossy dielectrics. We find that the material loss has an unexpected limited drawback and may even increase the bandwidth for low-index contrast systems.

Slow-light enhanced optical detection in liquid-infiltrated photonic crystals

Martin E. V. Pedersen, Lars Søgaard Rishøj, Henrik Steffensen +2 more

Slow-light enhanced optical detection in liquid-infiltrated photonic crystals is theoretically studied. Using a scattering-matrix approach and the Wigner–Smith delay time concept, we show that optical absorbance benefits both from slow-light phenomena as well as a high filling factor of the energy residing in the liquid. Utilizing strongly dispersive photonic crystal structures, we numerically demonstrate how liquid-infiltrated photonic crystals facilitate enhanced light–matter interactions, by potentially up to an order of magnitude. The proposed concept provides strong opportunities for improving existing miniaturized absorbance cells for optical detection in lab-on-a-chip systems.

Slow-light enhanced self-phase modulation, three-photon absorption and free-carriers in photonic crystals: experiment and theory

Chad A. Husko, Sylvain Combrié, Quynh Vy Tran +3 more

We demonstrate experimental results and analytical formulation of slow-light-enhanced self-phase modulation limited only by three-photon absorption. We present nonlinear figure-of-merits on three-photon-limited ultrafast switching, and critical intensities for free-carrier effects in photonic crystals.

Slow light enhanced nonlinear photonic functionalities

Marcel Spurny, Bill Corcoran, Christelle Monat +1 more

We discuss the enhancement of nonlinear functionalities in slow light photonic crystals. We show how slow light in photonic crystals is created, how nonlinear effects scale with the slowdown factor and what limits nonlinear effects in photonic crystals. We review some of the work recently reported in nonlinear optics in slow light photonic crystals and compare the observed effects to those found in other structures such as coupled resonators or photonic nanowires.

Flatband slow light in photonic crystals featuring spatial pulse compression and terahertz bandwidth

Michael Settle, Rob J. P. Engelen, M. S. Salib +3 more

Paradoxically, slow light promises to increase the speed of telecommunications in novel photonic structures, such as coupled resonators [1] and photonic crystals [2,3]. Apart from signal delays, the key consequence of slowing light down is the enhancement of light-matter interactions. Linear effects such as refractive index modulation scale linearly with slowdown in photonic crystals [3], and nonlinear effects are expected to scale with its square [4]. By directly observing the spatial compression of an optical pulse, by factor 25, we confirm the mechanism underlying this square scaling law. The key advantage of photonic structures over other slow light concepts is the potentially large bandwidth, which is crucial for telecommunications [5]. Nevertheless, the slow light previously observed in photonic crystals [2,3,6,7] has been very dispersive and featured narrow bandwidth. We demonstrate slow light with a bandwidth of 2.5 THz and a delay-bandwidth product of 30, which is an order of magnitude larger than any reported so far.

Slow light in photonic crystal waveguides

Thomas F. Krauss

The physical principles behind the phenomenon of slow light in photonic crystal waveguides, as well as their practical limitations, are discussed and put into context. This includes the nature of slow light propagation, its bandwidth limitation, the scaling of linear and nonlinear interactions with the slowdown factor as well as issues such as losses, coupling into and the tuning of slow modes. Applications in all-optical signal processing appear to be the most promising outcome of the phenomena discussed.
