    We designed and fabricated AlGaAs microdisks for efficient second-harmonic generation. Optical characterization confirmed whispering gallery modes at fundamental and second-harmonic wavelengths, crucial for future quasi-phase-matching studies.

    Area of Science:

    • Optoelectronics
    • Nonlinear Optics
    • Semiconductor Nanophotonics

    Background:

    • AlGaAs microdisks are promising for nonlinear optical applications.
    • Second-harmonic generation (SHG) is key for frequency conversion.
    • Whispering gallery modes (WGMs) enhance light-matter interaction.

    Purpose of the Study:

    • To design, fabricate, and optically characterize AlGaAs microdisks for SHG.
    • To investigate WGMs at fundamental and second-harmonic wavelengths.
    • To lay the groundwork for quasi-phase-matched nonlinear processes.

    Main Methods:

    • Fabrication of suspended AlGaAs microdisks on GaAs pedestals.
    • Optical characterization using spectroscopy.
    • Analysis of WGMs at telecom wavelengths.
