High-Output-Power Polarization-Insensitive Semiconductor Optical Amplifier

    Abstract—A high-output-power 1550 nm polarization-insensitive
    semiconductor optical amplifier (SOA) was developed for use
    as a compact in-line optical amplifier. A very thin tensile-strained
    bulk structure was used for the active layer and active width-tapered
    spot-size converters (SSCs) were integrated on both input
    and output sides. The SOA module exhibited a high saturation
    output power of +17 dBm together with a low noise figure of 7
    dB, large gain of 19 dB, and low polarization sensitivity of 0.2 dB
    for optical signals of 1550 nm wavelength. For the amplification
    of optical signals modulated at 10 Gb/s in the nonreturn-to-zero
    (NRZ) format, a good eye pattern without waveform distortion due
    to the pattern effect was obtained at an average output power of up
    to+12 dBm. Additionally, good amplification characteristics were
    demonstrated for the signal wavelength range corresponding to the
    C-band.
    Index Terms—Polarization insensitive, saturation output power,
    semiconductor optical amplifier (SOA), spot-size converter (SSC).
