All-InP metasurface operating at telecom wavelengths
Abstract
Abstract We propose and demonstrate an all-indium-phosphide (InP) metasurface that enables the monolithic integration of meta-optics with III–V semiconductor photonic devices. As a proof of concept, we designed a polarization-splitting metalens composed of InP nanoholes operating at telecom wavelengths and fabricated it using advanced compound-semiconductor processing techniques. The fabricated metalens exhibits a transmittance of 66.7% and polarization extinction ratios of 15.2 and 13.1 dB for x - and y -polarizations, respectively, demonstrating its suitability for optical communication applications. These results pave the way for the seamless integration of meta-optics with semiconductor photonics platforms.
