摘要： A system for lateral scanning of a sample using optical coherence tomography is presented. The low coherence interferometry system includes a first multiplexing unit and a second multiplexing unit. The first multiplexing unit is configured to receive a first beam of radiation and includes a first plurality of optical delay elements configured to introduce a group delay to the first beam of radiation based on an optical path traversed by the first beam of radiation among a first plurality of optical waveguides. The second multiplexing unit is configured to receive a second beam of radiation. The second multiplexing unit includes a second plurality of optical modulating elements configured to differentiate the second beam of radiation among a second plurality of optical waveguides to produce one or more output radiation beams. The second plurality of optical waveguides is configured to guide the one or more output radiation beams towards a sample.

摘要： A system for chromatic dispersion compensation is presented. The system includes an optical splitting element, a plurality of optical elements, and a plurality of waveguides. The optical splitting element is configured to generate at least a first beam of radiation and a second beam of radiation. The plurality of optical elements is configured to identify one or more optical paths amongst a plurality of optical paths for the first beam of radiation to travel. One of the plurality of waveguides disposed in one of the plurality of optical paths has group delay and dispersion coefficient properties per unit length that are different from group delay and dispersion coefficient properties per unit length of another one of the plurality of waveguides disposed in another one of the plurality of optical paths. The group delay and dispersion coefficient properties per unit length compensate for a chromatic dispersion associated with the second beam of radiation.

摘要： A system includes a waveguide that guides a beam of radiation, a variable delay unit, and a polarization-dependent modulating unit. The variable delay unit modulates the refractive index in a region, and the waveguide makes a plurality of passes through the region. The polarization-dependent element compensates for birefringence associated with the beam of radiation and includes a polarization splitter and a plurality of modulating elements. The polarization splitter has a first arm and a second arm that each include modulation segments. The beam of radiation is split between the first arm and the second arm and recombined after traversing the modulation segments. The recombination of the beam generates a first polarized beam of radiation and a second polarized beam of radiation. The plurality of modulating elements apply a first and second modulation to the first polarized beam of radiation and the second polarized beam of radiation respectively.
