    We developed a novel optical-level shifter and modulator using a quantum-well self-electro-optic effect device. This technology offers linear transmission control for optical processing and is compatible with semiconductor electronics.

    Area of Science:

    • Optoelectronics
    • Semiconductor devices
    • Quantum optics

    Background:

    • The quantum-well self-electro-optic effect (QSW-SEEO) device is a recently discovered optoelectronic component.
    • Existing optical modulators often lack linear response or compatibility with low-power electronics.

    Purpose of the Study:

    • To demonstrate a new negative-feedback mode of operation for QSW-SEEO devices.
    • To develop an optical-level shifter and a linear modulator based on this new mode.
    • To explore applications in analog and digital optical processing.

    Main Methods:

    • Utilized a novel negative-feedback operational mode of a quantum-well self-electro-optic effect device.
    • Integrated the device with laser diodes and low-power semiconductor electronics.
