  • Optical isolator, attenuator, circulator and switch
    Patent number: 9400403
    Abstract: An optical device comprising a first combination of birefringent prisms with parallel optic axes for dividing an optical input beam into polarized beams, a second combination of birefringent prisms with parallel optic axes for combining polarized beams into an output beam, a polarization changer, and means for improving isolation in optical isolators, attenuators and switches and for improving material costs, light transmission, size and beam capacity in optical isolators, attenuators, switches and circulators.
    Type: Grant

  • Optical isolator, attenuator, circulator and switch
    Publication number: 20060203340
    Abstract: A polarization independent optical isolator, attenuator, circulator and switch include at least a combination of birefringent prisms with parallel optic axes for dividing an input beam into parallel polarized beams or for combining parallels polarized beams into an output beam. In particular, an optical isolator (8) includes a first combination of birefingent prisms (10, 11), Farady rotator (12), half waveplate (13) and a second combination of birefringent prisms (14, 15). Devices may be conservative in the use of birefringent material, high in isolation and free from polarization mode dispersion.
