Abstract
Polarization-insensitive optical amplifiers are an alternative to current Erbium Doped Fiber Amplifiers, which provide wideband coverage while remaining cost and space effective for use in submarine cable applications. Polarization-insensitive optical amplifiers are an improvement to current semiconductor optical amplifier systems by providing desirable polarization-dependent gain and wideband coverage. This is achieved using polarization rotators comprised of a SOI-based waveguide and a twisted optical circuit.
