| Popis: | We propose an active plasmon lens (APL) consisting of a nanoslit array with an electrically tunable focal profile. Since the transmission phase of a nanoslit is a function of the slit width, applying bias to the nanoslit mechanically alters the nanoslit width and hence shifts the phase front. A proof-of-concept experiment demonstrates that applying a bias voltage of 5 V at 633 nm tunes the transmission profile of the fabricated APL. Our active lens is planar and only 400 nm thick, which gives it advantages for fabrication and integration. |
