Polarization-independent optical isolator in a Sagnac-type configuration [PDF]
Applied Optics, 2021 We propose a polarization-independent optical isolator that does not use walk-off between the two orthogonal polarizations. The design is based on two Faraday rotators in combination with two half-wave plates in a closed, Sagnac-interferometer-like configuration.
