THz third harmonic generation setup. A lowpass filter transmits a multicycle THz pulse, a graphene-based sample efficiently enables third harmonic generation, and a highpass filter helps improve its detection.

Silver nanoring metastructures designed via AI dramatically boost light absorption in ultra-thin silicon films, achieving high efficiency for solar and photonic applications.

CMOS wafer scale manufactured chiral exceptional point non-Hermitian modulators were demonstrated through AIM photonics. This enables GHz-speed asymmetric electro-optic modulation with 17 dB contrast using CMOS-compatible voltages.

Long-haul chaos synchronization of semiconductor lasers commonly driven by a digital optical fiber communication signal, which enables practical physical-layer encryption.

The non-Hermiticity of gain/loss can break the chiral currents in a Hall ladder, resulting in antichiral currents where currents on both legs co-propagate in the same direction.

This work employs a bidentate liquid agent to improve ligand coverage on QD surface, suppress ligand loss, and achieve a record ~23% EQE in _target NIR-LEDs.
