    Area of Science:

    • Terahertz (THz) optics and photonics
    • Microbolometer technology
    • Diffractive optics and microlens arrays

    Background:

    • Microbolometers are crucial for THz detection but often face limitations in sensitivity and coupling efficiency.
    • Diffractive microlenses offer potential for enhancing optical performance in the THz regime due to their design flexibility and fabrication compatibility.

    Purpose of the Study:

    • To design and fabricate a square diffractive microlens array for THz wave applications.
    • To integrate these microlenses with Niobium Pentanitride (Nb5N6) microbolometers on a single chip.
    • To evaluate the performance enhancement of microbolometers coupled with diffractive microlenses.

    Main Methods:

    • Fabrication of a five-staircase diffractive microlens array in the THz band.
    • Integration of Nb5N6 microbolometers with microlenses on a 4-inch silicon wafer.
    • Characterization of the focusing properties and coupling efficiency of the microlens array.
    • Measurement of voltage response, responsivity, and noise equivalent power (NEP) of the integrated microbolometers.

    Main Results:

    • The integrated diffractive microlens array demonstrated good focusing capabilities and improved coupling efficiency.
    • Microbolometers integrated with diffractive microlenses showed a 16-fold increase in voltage response compared to those on a silicon substrate.
    • Room-temperature detectors achieved a responsivity of 71 V/W and an NEP of 1.0 × 10^-10 W/Hz.
    • The diffractive microlens array is lightweight, has low absorption loss, and offers high resolution.

    Conclusions:

    • The fabricated diffractive microlens array effectively enhances the performance of THz microbolometers.
    • This technology offers a pathway for mass production using standard micro-fabrication techniques.
    • The integrated system shows promise for advanced THz sensing applications requiring high sensitivity and efficiency.
