“…To further enhance the effective nonlinearity, we have previously demonstrated the AlGaAs-on-insulator (AlGaAsOI) platform, where moderately low propagation loss (≤ 1.5 dB/cm) high-index contrast nanowaveguides can be realized with a high nonlinear coefficient. This platform has enabled efficient nonlinear processes such as FWM for wavelength conversion [25]- [28], and phasesensitive processing [29], as well as self-phase modulation (SPM) based supercontinuum generation [30].…”

Abstract-In this paper, we demonstrate wavelength conversion of advanced modulation formats such as 10-GBd 64-QAM and 256-QAM with high conversion efficiency over a 29-nm spectral window by using four-wave mixing in an AlGaAs-On-Insulator (AlGaAsOI) nano-waveguide. A thorough characterization of the wavelength converter is reported, including the optimization of the AlGaAsOI nano-waveguide in terms of conversion efficiency and associated bandwidth and the analysis of the impact of the converter pump quality and power as well as the signal input power. The optimized converter enables generating idlers with optical signal-to-noise ratio (OSNR) above 30 dB over a 29-nm bandwidth leading to error-free conversion of 64-QAM and 256-QAM with OSNR penalty below 1.0 dB and 2.0 dB respectively. The generated idlers exhibit an OSNR margin to the chosen forward error correction thresholds of >3 dB and >7 dB for 64-QAM and 256-QAM, respectively, that can be used for transmission after conversion.

“…We found different excitation regimes (slow and fast, hard and soft) and prove the robustness of the design. This system can be easily implemented in an up-to-date semiconductor platform for optical integrated circuits [6,24,25], but also in more advanced settings such as photonic crystal nanocavities,which are virtually monomodal and can exhibit very high Q-factors. This may permit to achieve compact microwave sources on an optical chip, operating in a frequency range inaccessible before, with important applications in telecommunications, sensing and metrology.…”

Stable integrated hyper-parametric oscillator based on coupled optical microcavities

We propose a flexible scheme based on three coupled optical microcavities which permits to achieve stable oscillations in the microwave range, the frequency of which depends only on the cavity coupling rates. We find that the different dynamical regimes (soft and hard excitation) affect the oscillation intensity but not their period. This configuration may permit to implement compact hyper-parametric sources on an integrated optical circuit, with interesting applications in communications, sensing and metrology.

We experimentally demonstrated 10 GHz frequency comb spectral broadening in an AlGaAsOI nano-waveguide with the peak power of only several watts. The spectral broadened 10 GHz frequency comb has high optical signal to noise ratio (OSNR) at the output of the nano-waveguide. As far as we know, it is the first photonic chip based frequency comb, relying on spectral broadening of a 10 GHz mode-locked laser comb in an AlGaAsOI nano-waveguide, with a sufficient comb output power to support several hundred Tbit/s optical data.
