    Abstract: A scanning device is presented having a substrate with a first surface and an opposite, parallel second surface. A region of the substrate includes the first surface and the opposite parallel second surface, and is defined via an etching process through a thickness of the substrate, where the region remains attached to the substrate via one or more hinges. A waveguide is patterned over the first surface of the region and guides a beam of radiation along a length of the waveguide. The scanning device includes a facet located on the first surface of the region. The facet is designed to reflect at least a portion of the beam of radiation through the region. An optical element is located on the second surface of the region, and is designed to receive the reflected portion of the beam of radiation.

  • Patent number: 9310185
    Abstract: Systems and methods are presented for modulating a beam of radiation, such that the modulated beam exhibits substantially null residual amplitude modulation (RAM). An electro-optical modulator is presented that includes a waveguide, a first region associated with the waveguide and a second region associated with the waveguide. The waveguide is designed to guide a beam of radiation. A first electric potential applied to the first region causes a first modulation to the beam of radiation while a second electric potential applied to the second region causes a second modulation to the beam of radiation. The first modulation combined with the second modulation provides substantially null residual amplitude modulation of the beam of radiation.

    Abstract: Systems and methods for use of the imaging system are presented. In an embodiment, the imaging system includes a first optical path, a second optical path, a plurality of optical elements, a detector, and a processor. The first optical path guides a first beam of radiation associated with epiluminescence while the second optical path guides a second beam of radiation associated with optical coherence tomography. The plurality of optical elements transmit the first and second beams of radiation onto a sample. The detector generates optical data associated with the first and second beams of radiation returning from the sample. The optical data associated with the first and second beams of radiation correspond to substantially non-coplanar regions of the sample. The processor correlates the optical data of the first beam with the optical data of the second beam and generates an image of the sample.

  • Publication number: 20140118748
    Abstract: 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.
