“…(7) as a starting point, we follow a standard diagonalization procedure of the operator to derive its eigenvalues and eigenvectors. After some 1 By means of simple analytical evaluations made on slab waveguides, one can quickly verify the validity of this assumption, as long as W G 1 remains reasonably far from the system made by W G 2 + W G 3 . In fact, given the transverse power distribution of the modes in this configuration, the overlap integral between W G 1 and W G 3 (which is roughly proportional to the coupling constant) appears to be vanishingly smaller than the one between W G 1 and W G 2 .…”

We characterize a system consisting of a two-mode waveguide coupled to a single-mode microring resonator possibly presenting a nonlinear response of Kerr type. By using the scattering parameter formalism extended to the multimode domain, we show that in the linear regime and for an ideally transparent medium, each resonance of the system can be exploited to perform complete even-to-odd (respectively, odd-to-even) modal conversion. Moreover, when the Kerr nonlinearity is effective, the microring enables a power-dependent modal switching mediated by phase bistability. Thanks to its mode-processing capabilities, this configuration is suitable to find application as a functional building-block in mode-division multiplexing (MDM) photonic integrated circuits.

“…Figures 4(a) and 4(b) show the evolutions of the temporal pulse and normalized output spectrum along propagation distance in the waveguide when the variation of γ(z), α 0 , 3PA, HON, and HOD are all considered. α 0 is chosen as 0.026 dB/cm [41][42][43] and the 3PA coefficient γ 3PA is 0.028 cm 3 /GW 2 [30]. HOD coefficients are considered up to 6-th order.…”

“…However, α 0 may vary significantly depending on the fabrication techniques of the waveguide, which should be investigated in practice. The scattering by voids, damages and rough surfaces of the waveguide, along with the material absorption, are the dominant sources of loss [41]. With well-designed cross-section of the waveguide and optimized lithography and dry etching processes to reduce the sidewall roughness, α 0 can be reduced to 0.274 dB/cm [45].…”

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).

Two-dimensional materials have emerged as promising candidates to augment existing optical networks for metrology, sensing, and telecommunication, both in the classical and quantum mechanical regimes. Here, we review the development of several on-chip photonic components ranging from electro-optic modulators, photodetectors, bolometers, and light sources that are essential building blocks for a fully integrated nanophotonic and quantum photonic circuit.
