LAUNCH OPTICS WITH OPTICAL PATH COMPENSATION FOR A WAVELENGTH SELECTIVE SWITCH |
摘要 |
An optical device includes an optical port array, a first walk-off crystal, a first half-wave plate, a second walk-off crystal and a segmented half-wave plate. The optical port array has a first and second plurality of ports for receiving optical beams. The first walk-off crystal spatially separates the beams into first and second portions that are in first and second orthogonal polarization states, respectively. The first portions are walked-off by the first walk-off crystal and the second portions pass therethrough without being walked-off. The first half-wave plate rotates the polarization state of the first and second portions of the optical beams. The second walk-off crystal is oriented in an opposite direction from the first walk-off crystal such that the second portions are walked-off by the second walk-off crystal and the first portions pass therethrough without being walked-off. The segmented half-wave plate receives the first or second portions of the beams. |
