    Area of Science:

    • Optical Engineering
    • Wireless Communication
    • Oceanography

    Background:

    • Underwater optical wireless communication (UOWC) faces challenges in data rate and transmission distance.
    • Coherent detection offers potential for improved performance but requires complex systems.
    • Existing UOWC systems often lack the capacity for next-generation underwater data transmission needs.

    Purpose of the Study:

    • To propose and experimentally validate an effective underwater coherent optical wireless communication (UCOWC) method with a simplified detection scheme.
    • To investigate the Bit Error Rate (BER) performance under varying underwater channel attenuations.
    • To determine the maximum achievable attenuation length (AL) for different modulation schemes below the Forward Error Correction (FEC) limit.

    Main Methods:

    • Proof-of-concept experiments using M-ary Phase Shift Keying (PSK) modulation.
    • Utilized a common laser for both signal source and local oscillator (LO) to simplify the system.
    • Evaluated BER performance across different attenuation lengths and data rates (500 Mbps to 1.5 Gbps).

    Main Results:

    • Achieved data rates of 500 Mbps (BPSK), 1 Gbps (QPSK), and 1.5 Gbps (8PSK).
    • Measured maximum achievable attenuation lengths of 13.4 AL (BPSK), 12.5 AL (QPSK), and 10.7 AL (8PSK) with BER below 3.8×10-3.
    • Estimated performance degradation when using separate free-running lasers for signal and LO.

    Conclusions:

    • The proposed simplified coherent detection scheme is effective for UCOWC.
    • This approach enhances data transmission capacity and extends the achievable distance in underwater environments.
    • Paves the way for practical UCOWC systems meeting future underwater communication demands.
