“…Compared with the dynamic control required in the drawing of a fiber taper, controlling the waveguide dimension of on-chip devices is much easier. Self-similar compression of a pulse from 1 ps to 81.5 fs in a 6 cm long dispersion decreasing chalcogenide slot waveguide taper has been demonstrated by simulation [23]. However, further compression under the self-similar scheme in such a slot waveguide is limited by the two-photon absorption (TPA) of the substrate material and higher-order dispersion (HOD).…”

“…But the long fiber length required is undesirable in most systems because of compactness and cost [16][17][18]. Compared with the adiabatic compression, self-similar pulse compression can achieve large compression factor without pedestal generation in much shorter nonlinear media [3,[19][20][21][22][23]. In a 6.4 m nonlinearity increasing photonic crystal fiber (PCF) taper, a 1 ps pulse is self-similarly compressed to 53.6 fs with low pedestal [3].…”

“…Adopting silicon waveguide will greatly promote the development of on-chip scale nonlinear photonics [25][26][27][28]. In the near-infrared spectral region around 1.55 μm, the TPA in silicon has a significant effect [23,29], which greatly limits the output optical power and degrades the efficiency of nonlinear optical processes. TPA can be greatly reduced in the mid-infrared spectral region.…”

Abstract:On chip high quality and high degree pulse compression is desirable in the realization of integrated ultrashort pulse sources, which are important for nonlinear photonics and spectroscopy. In this paper, we design a simple inversely tapered silicon ridge waveguide with exponentially decreasing dispersion profile along the propagation direction, and numerically investigate self-similar pulse compression of the fundamental soliton within the mid-infrared spectral region. When higher-order dispersion (HOD), higher-order nonlinearity (HON), losses (α), and variation of the Kerr nonlinear coefficient γ(z) are considered in the extended nonlinear Schrödinger equation, a 1 ps input pulse at the wavelength of 2490 nm is successfully compressed to 57.29 fs in only 5.1-cm of propagation, along with a compression factor F c of 17.46. We demonstrated that the impacts of HOD and HON are minor on the pulse compression process, compared with that of α and variation of γ(z). Our research results provide a promising solution to realize integrated mid-infrared ultrashort pulse sources. Richardson, and U.

In the fast‐growing field of integrated photonics, quantifying the dispersive characteristics of the optical components integrated on chip is of key importance. The short length of on‐chip components, however, makes it challenging to measure their dispersive properties. Hence, experimental data are relatively scarce, especially at wavelengths close to the zero‐dispersion wavelength (ZDW) where the dispersion‐length product becomes very small. Ideally, the dispersion should be characterized with a technique that, besides being highly sensitive, “directly” yields the dispersion value without frequency derivative calculations nor the addition of dedicated on‐chip measurement structures. To fulfill these requirements, a dispersion characterization technique is presented relying on femtosecond‐resolution time‐of‐flight measurements combined with advanced spatial light modulator (SLM) technology. With this new “direct” technique, suitable for measuring dispersion‐length products down to 5 × 10−5 ps nm−1, the dispersion of mm‐length silicon nitride waveguides is characterized, both in the weakly dispersive (close to the ZDW) and strongly dispersive regimes. Furthermore, dispersion data are presented for sub‐mm‐length trident couplers and inverted taper couplers connected to the waveguides. The resulting insights into the waveguides’ and couplers’ dispersive properties, and the wide applicability of the technique, will benefit the development of advanced photonic integrated circuits (PICs) in silicon nitride and other waveguide material platforms.
