Until now, the fastest optic chips have integrated electric elements called modulators. These modulators execute a light and data conversion process: they change luminous energy into electric energy and the reverse process, which causes high-complexity optical chips and high-energy taking.

A group of investigators from Yale University and from Washington University developed a chip that integrates a modulator that works light based instead of electrostatic force based. They confined laser light in an on-chip silicon waveguide to create the modulator. The waveguide leads light through a narrow silicon section. This silicon beam so-called nanomechanical resonator transmits the optical signal and modulates it. When the luminous signal passes by the integrated circuit and laser light projects over the nano-optical modulator, it produces an oscillation that modulates the light that travels through the beam. This investigation group also proved that is possible to perform matrixes of cents of running resonators in only one chip, although they still have to incorporate the laser into the chip.
