  • An acoustic wave can induce non-reciprocal light modulation in a silicon waveguide. Now, the acoustic wave has been induced optically in a neighbouring silicon waveguide, opening the way for a silicon-based optical isolator.

  • Front-induced transitions have been used in dispersion-engineered waveguides for frequency conversion, optical delays, and bandwidth and pulse duration manipulation. This Review provides a theoretical description of the subject and highlights the potential for light manipulation in guided optics.
