    摘要: A high dynamic range integrated (HDRI) receiver includes a variable optical attenuator (VOA) for attenuating an incoming optical signal before the optical signal is directed to a photo-detector for conversion into an electrical signal. An optical block receives the optical signal from an optical fiber and includes optics for directing the optical signal to the VOA, and for directing the optical signal from the VOA to the photo-detector.

    摘要: An optical system for producing electromagnetic radiation with localized increases in irradiance or radiance at the system output includes a first optical mask containing localized regions for producing controlled modifications of phase delays and/or amplitude attenuations and located within the input plane of said optical system. The system also includes at least a single optical component with positive optical power located after the input plane and at least one additional optical mask located after the optical component at non-conjugate locations with respect to the input plane of the system. The additional optical mask contains localized regions for producing controlled modifications of phase delays. Locally increased radiation distributions are produced at the system output.

    摘要: A diode laser beam combining apparatus for producing a high combined beam power density in the far field at reduced levels of power consumption and heat dissipation includes an array of semiconductor laser emitters arranged in a collinear manner with respect to each other and having an emitter pitch between about 0.7 mm and 2.5 mm. The apparatus also includes a cylindrical lens for collimating emitter beams generated by the array of laser emitters in a direction perpendicular to a junction plane of the laser emitters. The apparatus further includes a micro-optic array and a long focal length cylindrical lens. The micro-optic array is configured to perform a rotational transformation of the collimated emitter beams. The micro-optic array has a lateral spacing in a direction parallel to the junction plane of the laser emitters that matches the emitter pitch. The long focal length cylindrical lens collimates emitter beams in the direction perpendicular to the junction plane after passing through the micro-optic array.

    摘要: The linear dispersion of a dispersive optical system is increased by: (a) employing a transmissive diffraction grating (6) as a dispersive element; and (b) passing light through the grating twice. A reflector (7) is used to achieve the double passage through the grating. The system can be used to disperse light into its composite wavelengths (e g., the system can be a wavelength demultiplexer) or to combine dispersed light at different wavelengths into composite light (e.g., the system can be a wavelength multiplexer). The system can be employed in wavelength division multiplexed (WDM) optical communication systems.

    摘要: A vehicle headlamp may be formed from a light source; a divergent lens; and a reflector facing in a forward direction to the lens. The reflector has one or more first regions, and one or more second regions. The first region is a section of an ellipsoid of revolution with one focal point coincident with the light source, and one focal point located at the first focal point of the lens. The second regions have a surface with an elliptical vertical cross section having a first focal point coincident with the light source and a second focal point coincident with the first focal point of the lens. The second surface additionally has a horizontal axial cross section having a first focal point coincident with the light source and a second focal point axially offset from the first focal point of the lens. The horizontal axial cross section may be elliptical, parabolic or hyperbolic. Light from the first regions is convenient to form the beam hot spot. Meanwhile, light from the second regions is convenient to form the beam spread. In total the system provides a headlamp with a short axial dimension and a small frontal opening while meeting headlamp beam standards.

    摘要: A wavelength monitoring device for monitoring a beam of light is disclosed having a beam splitter, with opposing first and second spaced apart faces, for receiving optical radiation from the beam of light to be monitored. In operation the first face reflects a first portion of the optical radiation to a first photodiode. The second face includes a grating for reflecting a second portion of the optical radiation to the first photodiode. The grating also reflects a third portion of optical radiation to a second photodiode. The light received by the second photodiode corresponds proportionally to optical power of the incident beam of light. The first photodiode is for detecting a wavelength characteristic of the composite beam and is located so as to receive the first portion and the second portion of optical radiation after the first portion and the second portion of optical radiation have optically interfered to form a composite beam. The first face and the grating are oriented and spaced from one another so that the first and second portions of the optical radiation optically interfere with one another along a path toward the first photodiode.
