    A novel multi-wavelength fiber sensing system utilizes a linear cavity laser and a semiconductor optical amplifier for efficient multi-point measurements. This system demonstrates stable lasing and accurate temperature sensing, offering a simple yet effective solution.

    Area of Science:

    • Optoelectronics
    • Fiber Optics Sensing
    • Laser Physics

    Background:

    • Multi-point fiber sensing is crucial for distributed measurements.
    • Existing methods like Fiber Bragg Gratings (FBG) and Brillouin scattering have limitations.
    • A simpler, efficient multi-channel sensing system is needed.

    Purpose of the Study:

    • To propose and investigate a novel multi-point fiber sensing system.
    • To analyze the impact of optical nonlinearity in a semiconductor optical amplifier (SOA) on multi-channel sensing.
    • To demonstrate and validate the system's performance for temperature sensing.

    Main Methods:

    • Theoretical investigation of lasing conditions in a linear cavity laser with SOA, Arrayed Waveguide Grating (AWG), and FBGs.
    • Analysis of gain saturation and four-wave mixing effects in the SOA.

    Related Experiment Videos

  • Experimental demonstration of multi-wavelength lasing and two-channel temperature sensing using FBGs and AWG.

    • Main Results:

    • Multi-wavelength lasing power is primarily limited by SOA gain saturation.
    • An eight-channel system achieved -8.5 dBm lasing power with 10 dB total cavity loss.
    • Lasing power increased by 3 dB when reducing channels from eight to four.
    • Experimental demonstration confirmed up to eight-channel lasing and two-channel temperature sensing (13°C–76°C).

    Conclusions:

    • The proposed linear cavity laser system offers a simple and effective approach for multi-point fiber sensing.
    • SOA gain saturation is a key factor limiting lasing power in multi-channel configurations.
    • The system is experimentally validated for accurate temperature sensing applications.
