Abstract: The disclosure relates to an optical device for wavelength division multiplexing of two or more input beams. The disclosure proposes the optical device, and a corresponding method for operating the optical device. The optical device comprises a multiplexer and two or more channels for the two or more input beams, wherein each channel is configured to receive one input beam of the two or more input beams and to provide a rotated beam, which has a polarization rotated compared to a polarization of the corresponding input beam, to the multiplexer, and wherein at least one channel of the two or more channels is configured to rotate the polarization of the corresponding input beam in a different direction than at least one other channel of the two or more channels.
