Innovating ENZ Materials for Next-Generation Photonics
Scientists have discovered a groundbreaking method of manipulating light emission by temporarily transforming ordinary liquids into epsilon-near-zero (ENZ) materials using intense femtosecond laser pulses. Real part of the dielectric function of isopropanol (IPA) without optical excitation (black line) and with optical excitation leading to three different electron concentrations of 50, 100 and 200 μM (colored…
