  • Quasi-phase matching enhances nonlinear optics but typically requires fixed material changes. Here, authors demonstrate the first optically programmable quasi-phase matching in standard fibers, enabling broadband, tunable wavelength conversion over 298 nm without altering the fiber.

  • Light guiding typically relies on modifying the material’s linear permittivity. Here, guided wave circuits of frequency-superposition light beams are realized without changing the linear refractive index, by modifying the material’s nonlinearity, enabling all-optical controlled photonic devices.

  • Airy beams have so far been generated by linear diffractive elements. Now, scientists show that they can also be created by a nonlinear process, opening the door to all-optical beam control and production at wavelengths unavailable by conventional methods.

  • An analogous all-optical Stern–Gerlach experiment is observed in nonlinear optics, where the frequency of light acts as a pseudospin. The deflection depends on the strength of the nonlinear coupling gradient as well as on the relative phase between the different input frequencies.

  • The diffraction of electrons through a nanoscale hologram that imprints a certain phase modulation on the electrons’ wavefunction produces a non-spreading electron Airy beam that follows a parabolic trajectory and can reconstruct its original shape after passing an obstacle.

  • Since 1974, it was theoretically postulated that black holes, despite their name, emit radiation with a spectrum like that of a black body. Utilizing surface gravity water waves to emulate black hole physics, the authors reveal the emergence of a logarithmic phase singularity analogous to that predicted by Hawking in black holes, whose energy distribution associated with the singularity results in a Fermi-Dirac distribution instead of the familiar Bose-Einstein statistics of the Hawking radiation.
