Abstract

We report an all-dielectric active metasurface based on indium phosphide (InP) multiple quantum wells (MQWs) operating at telecom wavelengths (λ=1.55μm). Our design exhibits high reflectance of >80% and is based on localized Mie supported by the metasurface. Our calculations show that the proposed metasurface can steer the beam up to polar angles of 35° while maintaining high efficiency of >80% and a side mode suppression ratio of 7 dB. The anticipated modulation frequencies are >1 MHz. Our metasurface can be used in future chip-scale light detection and ranging systems as well as for free-space optical communications.
