    Summary

    We demonstrate optical bi-stability in silicon-rich nitride (SRN) films for memory and sensing. The study confirms a thermal mechanism for bi-stable switching with a relaxation time of 18.7 microseconds.

    Area of Science:

    • Materials Science
    • Optoelectronics
    • Nonlinear Optics

    Background:

    • Silicon-rich nitride (SRN) films are promising for photonic applications due to their tunable optical properties.
    • Optical bi-stability is crucial for developing advanced optical switches and memory devices.
    • Understanding the nonlinear optical response of SRN is essential for device optimization.

    Purpose of the Study:

    • To investigate and demonstrate optical bi-stability in a PECVD-grown SRN film.
    • To characterize the thermo-optic coefficients and nonlinear optical properties of the SRN material.
    • To explore the potential of SRN for optical switching, memory, and thermal sensing.

    Main Methods:

    • Fabrication of an SRN ring resonator device using plasma-enhanced chemical vapor deposition (PECVD).
