Heating-free, room-temperature operation of a radiofrequency-to-light signal transducer with a membrane oscillator and a built-in metasurface mirror

Abstract We present an electro-mechano-optical radiofrequency (rf)-to-light signal transducer robust against laser heating and thus operational at room temperature. A metal-free, low-loss metasurface mirror aluminum electrode made separately on a Si 3 N 4 membrane oscillator comprise chain of electro-mechanical opto-mechanical systems, mediating electrical optical signals through the (2,2)-mode characteristic oscillation. demonstrate up-conversion rf 175.2 MHz by 6 orders magnitude in frequency to regime with transfer efficiency 2.3×10 -9 , also showing stable operation due reduced mirror.
