“…In [99], an all-optical exclusive OR logic gate was also demonstrated with a m 396 m long silicon PhC waveguide owing to the largeslow-down enhancement (n g =32) at an estimated energy of 1 pJ/bit. Other applications such as wavelength conversion [100,101], demultiplexing [102,103], signal amplification [104] and regeneration [105,106] have been demonstrated in those platforms.…”

This review is devoted to integrated photonic platforms based on large band-gap semiconductors, alternatives to silicon photonics. The large electronic band gap of the material employed is chosen to address the specific needs of nonlinear optics, and, in particular, lower nonlinear losses and the capability of handling larger optical power densities. Moreover, these new platforms offer broader transmission spectra, extending to the visible spectral region, which is also required for other applications, particularly sensing and bio-related photonics. The focus is on nanoscale patterned waveguiding structures, which, owing to the tight confinement of light, have demonstrated a large nonlinear response. The third-order nonlinear response and the related parametric interactions will be considered here, encompassing four-wave mixing, phase-sensitive amplification, wavelength conversion, and also nonlinear pulse propagation and soliton dynamics. The comparison between different materials and waveguide design highlights specific features of photonic crystal waveguides.

“…(11) can be used in the case where the TPA nonlinear losses can be suppressed. This is usually accomplished concerning materials possessing lower TPA coefficient (β TPA ) frequently referred to as TPA-free materials [23]- [25], which are currently receiving increased attention in signal processing applications. Although this result is known and frequently used in the literature, its derivation provides the underlying idea used in the next sections.…”

Approximate expressions for estimation of four-wave mixing efficiency in slow-light photonic crystal waveguides

2014

We present approximate analytical expressions for the estimation of the degenerate four-wave mixing conversion efficiency in slow light photonic crystal waveguides. The derived formulas incorporate the different effective modal areas and the frequency-dependent linear and nonlinear parameters of the pump, signal and idler waves. The influence of linear loss, two-photon absorption and free-carrier generation is also accounted for. Numerical solution of the coupled propagation equations is used to verify the validity of the proposed expressions under different values of the linear and nonlinear parameters of the waveguide. It is shown that the derived expressions provide an accurate estimation of the conversion efficiency and are thus expected to be very useful in the design of photonic crystal waveguides for nonlinear signal processing applications.

“…The incorporation of nonlinear nanoscale waveguides, such as nanowires (NWs) and photonic crystals (PhCs), within integrated optical circuits offers flexible processing capabilities including wavelength conversion [1,2], demultiplexing [3,4], and pulse reshaping by soliton propagation and compression [5]. The nonlinearity of most reported nanoscale waveguides is also sufficient for idler generation by four-wave mixing (FWM).…”

We report on a chip scale parametric amplifier based on a GaInP photonic crystal waveguide. The amplifier operates with both pump and signal in the 1550 nm wavelength range and offers an on-chip gain of 11 dB (5 dB including the 6 dB coupling losses) when pumped at only 800 mW. It enables us, therefore, to incorporate the many advantages of parametric amplification within photonic chips for optical communication applications.
