摘要： Various configurations of a virtually imaged phased array (VIPA) generator in combination with a mirror to compensate for chromatic dispersion. A VIPA generator produces a light traveling from the VIPA generator. In some embodiments, a variable curvature mirror is positioned to reflect the light back to the VIPA generator. A rotation axis around which the mirror is rotated and a translation path for the rotation axis are provided, to change the curvature of the mirror where the output light is reflected. In other embodiments, a plurality of mirrors have different surface curvatures. A holder has a rotation axis and holds the plurality of mirrors equidistantly from the rotation axis. The holder is rotatable around the rotation axis to bring a different, respective mirror in position to reflect light produced by a VIPA generator back to the VIPA generator. In other embodiments, a rotating mirror is rotatable about a rotation axis to reflect light produced by a VIPA generator to a respective fixed mirror. In still other embodiments, an off-axis parabolic mirror is rotatable about a rotation axis to reflect light produced by a VIPA generator to a respective fixed mirror.

摘要： Techniques and devices for emulating polarization-mode dispersion in an optical signal that transmits through an optical fiber by using multiple birefringent wave-guiding sections that are interconnected to have adjustable polarization-changing connectors. The polarization of light transmitting from one section to another adjacent section can be modified differently between different adjacent sections according to a distribution function to produce one PMD state to represent one possible PMD state of a real PMD fiber. The connectors can be adjusted to produce different sets of polarization modifications to produce different PMD states to represent different possible PMD states of the real PMD fiber.

摘要： A system and method to chromomodally generate dispersion in light waves. The system and method may be used to control dispersive effects of an optical element such as a single-mode fiber. A light beam from the optical element is first collimated and then directed on to a spatially diffractive element where it is spatially dispersed into various chromatic frequency components. This frequency-separated light is then imparted onto a dispersion slope equalizer, and then passed into a highly multimode waveguide, where it is further dispersed. The light is then collected and focused back into an outgoing fiber-optic or other optical device.
