AI Article Synopsis

  • The study focuses on how two light pulses (pump and probe) interact when passing through a thin, nonlinear material that has a specific property called epsilon-near-zero (ENZ).
  • When the probe pulse's wavelength aligns closely with the ENZ wavelength, its transmission is significantly influenced by the intensity of the pump pulse, showing a strong modulation effect.
  • If the probe pulse is outside the ENZ wavelength range, its transmission remains largely unchanged by the pump, indicating that the ENZ regime is extremely sensitive to optical inputs.

Article Abstract

We investigate the interaction of two pulses (pump and probe) scattered by a nonlinear epsilon-near-zero (ENZ) slab whose thickness is comparable with the ENZ wavelength. We show that when the probe has a narrow spectrum localized around the ENZ wavelength, its transmission is dramatically affected by the intensity of the pump. Conversely, if the probe is not in the ENZ regime, its propagation is not noticeably affected by the pump. Such all-optical modulation is due to the oversensitive character of the ENZ regime, and it is so efficient that it even occurs in a wavelength thick slab.

Graphene has unique properties paving the way for groundbreaking future applications. Its large optical nonlinearity and ease of integration in devices notably makes it an ideal candidate to become a key component for all-optical switching and frequency conversion applications. In the terahertz (THz) region, various approaches have been independently demonstrated to optimize the nonlinear effects in graphene, addressing a critical limitation arising from the atomically thin interaction length.

The inherent potential for self-assembly is a well-known attribute of organic dye molecules. This work takes advantage of the changes in dye photochemical and photophysical properties produced by the aggregation phenomenon, to investigate the behavior of all-optical modulation in molecular aggregates. The theoretical principles for a dual beam all-optical modulation, as well as the conception of an optical logic gate by exploring the aggregation phenomenon are discussed throughout the article.

We integrate monolayer TMDCs into silicon-on-insulation (SOI) waveguides and dielectric-loaded surface plasmon polariton (DLSPP) waveguides to enhance nonlinear parameters (γ) of silicon-based waveguides. By optimizing the waveguide geometry, we have achieved significantly improved γ. In MoSe-on-SOI and MoSe-in-DLSPP waveguide with optimized geometry, the maximum γ at the excitonic resonant peak (λ) is 5001.

A compact and robust optical excitation photoacoustic sensor with a self-integrated laser module excitation and an optimized differential resonator was developed to achieve high sensitivity and full linear range detection of carbon dioxide (CO) based on dual modes of wavelength modulated photoacoustic spectroscopy (WMPAS) and resonant frequency tracking (RFT). The integrated laser module equipped with three lasers (a quantum cascade laser (QCL), a distributed feedback laser (DFB) and a He-Ne laser) working in a time-division multiplexing mode was used as an integrated set of spectroscopic sources for detection of the designated concentration levels of CO. With the absorption photoacoustic mode, the WMPAS detection with the QCL and DFB sources was capable of CO detection at concentrations below 20 %, yielding a noise equivalent concentration (NEC) as low as 240 ppt and a normalized noise equivalent absorption coefficient (NNEA) of 4.

Ultrafast all-optical control has been a subject of wide-spread attention as a method of manipulating optical fields using light excitation on extremely short time scales. As a fundamental form of ultrafast all-optical control, all-optical switching has achieved sub-picosecond switch speeds in the visible, infrared, and terahertz spectral regions. However, due to the lack of suitable materials, ultrafast all-optical control in the ultraviolet range remains in its early stages.
