On‐chip electro‐optic and optoelectric dual modulation is realized by Xiaoyong Hu and coworkers (article number 1800374 ) using a ZnO nanowire covered photonic‐crystal nanocavity. A weak 0.4‐microwatt signal light induces large modulation‐depth of 60% in the electric signal, while a small gate voltage of 1.5 Volt induces large modulation‐depth of 75% for the signal light. This paves the way for achieving on‐chip photon–electric signal interconversion, and multifunctional optoelectronic integrated devices.
