## Description

- description: Devices based on two-dimensional (2D) semiconductors hold promise for
    the realization of compact and versatile on-chip interconnects between electrical
    processors and optical transmission lines. Although light emitting diodes (LEDs)
    and lasers are fundamental building blocks for the realization of optical interconnects,
    the integration of conventional light sources made of classical semiconductors
    to complementary metal- oxide-semiconductor (CMOS) integrated circuits remains
    challenging. While LEDs based on van der Waals heterostructures have been realized,
    the electrical control of the emission properties necessary for information processing
    remains limited. Here, we show for the first-time room-temperature electrical
    control of the location, directionality and polarization of light emitted from
    a 2D LED operating at MHz frequencies. We integrate the LED in a planar cavity
    to couple the photon emission angle to the in-plane exciton momentum, controlled
    by a lateral voltage. We further demonstrate circularly polarized photon emission
    coupled to the electrically generated valley polarization of electrons and holes.
    These findings demonstrate the potential of TMDCs as fast, compact and tunable
    light sources for the development of next-generation integrated photonics. Our
    cavity-coupled LED has potential for the development of electrically driven polariton
    lasers9 compatible with CMOS technology.
