摘要： A multiple target optical imaging apparatus performs optical imaging of a plurality of physically-separated imaging sites using a light source, a two-dimensional detector and a plurality of fiber bundles. Each fiber bundle has a distal end positioned adjacent to a different one of the imaging sites, and conveys source light from its proximal end to its distal end, while conveying an optical signal from its respective imaging site from its distal end to its proximal end. The optical signals may be simultaneously detected on different regions of the detector. The system is small, and may be used to image sites on an ambulatory animal, with the light source and detector located in a portable housing attached to the animal. Different types of imaging may be used, including fluorescence imaging, hyperspectral imaging, or polarization imaging.

摘要： An optical signal may be received into orthogonal linearly polarized modes of a transmission optical waveguide, the transmission waveguide including first and second transverse-coupling segments thereof. Optical signal polarized along one polarization direction may be substantially completely transferred from the transmission waveguide into a first transverse-coupled waveguide, the first transverse-coupled waveguide being optically transverse-coupled to the first transverse-coupling segment of the transmission waveguide. Optical signalpolarized along the other polarization direction may be substantially completely transferred from the transmission waveguide into a second transverse-coupled waveguide, the second transverse-coupled waveguide being optically transverse-coupled to the second transverse-coupling segment of the transmission waveguide. The optical signals carried by the first and second transverse-coupled waveguides may be combined into a single waveguide. The polarization directions of the transmission waveguide may be rotated about 90° between the first and second transverse-coupling segments

摘要： A chiral in-fiber tunable polarizer implemented in a chiral fiber structure is provided. The chiral fiber is selected with a predetermined handedness and scatters (by reflecting, coupling into the fiber core or otherwise) the circularly polarized light matching its handedness while transmitting circularly polarized light of opposite handedness. By combining the chiral fiber with another fiber component having a non-cylindrical core, the inventive apparatus produces a linearly polarized wave with a predetermined orientation. The orientation may be adjusted by rotating the fiber component around its central axis. The chiral fiber structure may be configured as a long period chiral fiber grating. Optionally, the chiral fiber structure may be configured with a variable pitch along its length, such as a chirped fiber grating, an apodized fiber grating, or a set of multiple sequential chiral polarizer elements with different pitches. This variable pitch arragement results in output light having a configurable polarization spectrum of a predetermined shape.

摘要： A proton exchange polarizer with a spatial filter positioned to reduce cross coupling of unguided radiation. A photoconductor substrate is fabricated from LiNbO3 or LiTaO3. The substrate has a spatial filter located at a primary reflection point on a bottom of the substrate so as to block unguided TM mode light from reaching the output of the substrate. The spatial filter is fabricated by physical or chemical methods such as saw cutting, diamond machining, etching, micro-machining, laser-machining and/or damaging the surface of the substrate. The unguided TM mode light is attenuated by blockage or interruption of the transmissive region.

摘要： A radiation-emitting device (e.g., a laser) includes an active region configured to generate a radiation emission linearly polarized along a first polarization direction and a device facet covered by an insulating layer and a metal layer on the insulating layer. The metal layer defines an aperture through which the radiation emission from the active region can be transmitted and coupled into surface plasmons on the outer side of the metal layer. The long axis of the aperture is non-orthogonal to the first polarization direction, and a sequential series of features are defined in or on the device facet or in the metal layer and spaced apart from the aperture, wherein the series of features are configured to manipulate the surface plasmons and to scatter surface plasmons into the far field with a second polarization direction distinct from the first polarization direction.
