analiza aiqbench
Physicists at TU Graz have engineered a metasurface using quantum wells to amplify nonlinear polarization conversion by 72,000 times compared to standard materials. This breakthrough enables compact photonic circuits that operate at room temperature, addressing previous limitations regarding the need for high-power lasers or bulky crystals. The advancement significantly lowers barriers for integrating nonlinear photonics into practical quantum technologies and ultra-precise sensing applications.
