SKU: SOAB
The SOAB is a high-saturation-output-power, high-bandwidth, low-noise booster optical amplifier. It features a highly efficient InP/InGaAsP Quantum Well (QW) layer structure and a reliable ridge waveguide design, ensuring robust performance. The amplifier is housed in a standard 14-pin butterfly package, complete with an integrated thermoelectric cooler (TEC) and thermistor for precise thermal management. The SOAB is polarization-insensitive, amplifying all polarization states, making it an excellent choice for in-line amplification. It is available with either single-mode (SM) or polarization-maintaining (PM) fiber pigtails, both terminated with FC/APC connectors. For PM-fiber-pigtailed models, the connector key is aligned to the slow axis. Options include configurations with no isolators or polarization-insensitive isolators at the input, output, or both, to eliminate reflection induced noise. The SOAB provides a versatile and reliable solution for optical amplification needs.
The basic working principle of an SOAB is the same as a semiconductor laser but without feedback. SOABs amplify incident light through stimulated emission. When the light traveling through the active region, it causes these electrons to lose energy in the form of photons and get back to the ground state. Those stimulated photons have the same wavelength as the optical signal, thus amplifying the optical signal.
