  • Spotlight Summary by Steven Cundiff

    • High-speed two-dimensional terahertz spectroscopy with echelon-based shot-to-shot balanced detection
    • The concept of multidimensional spectroscopy was developed in nuclear magnetic resonance in the 1960s and 1970s. Its ability to reveal coupling between nuclear spins was revolutionary. Over the last couple of decades,...

Light–Matter Interactions

  • Spotlight Summary by Kevin C. Zhou

    • Simultaneous multiple time scale imaging for kHz–MHz high-speed accelerometry
    • Current high-speed imaging technology forces us to make several compromises, one of which is the tradeoff between the imaging speed and the recording duration. Specifically, at frame rates in the MHz to GHz regime, one...

  • Spotlight Summary by Ilya Shadrivov

    • High-efficiency reflective metasurfaces for terahertz vortex wave generation based on completely independent geometric phase modulations at three frequencies
    • Artificially structured surfaces, or metasurfaces, have their functionality defined by the actual structure. Quite often the desired electromagnetic properties are achieved just in a narrow frequency range, because the...

  • Spotlight Summary by Marco Piccardo

    • Ultra-broadband flat-top quantum dot comb lasers
    • A chip-scale broadband frequency comb emitting in the telecom range useful for multiplexed communications was demonstrated, thanks to advances in the design of quantum dot lasers. In wavelength-division multiplexing...

  • Spotlight Summary by Vassilios Kapaklis

    • Light-induced thermomagnetic recording of thin-film magnet CoFeB on silicon waveguide for on-chip magneto-optical memory
    • Bringing up the term “speed of light” often makes us think of velocities, but there is more to it, as light can induce ultrafast changes to properties of condensed matter. A prominent example is the...
