摘要： A compact optical isolator includes a polarizer, a Faraday rotator, and an analyzer that are arranged in series. A magnet is also included to provide a magnetic field to the Faraday rotator. The outer edges of the polarizer, Faraday rotator, and analyzer are preferably parallel to each other and to the optical path of the incoming light beam so that the optical aperture through the optical isolator is maximized. In addition, each of the polarizer, the Faraday rotator, and the analyzer have at least one facet in the optical path of the light beam that is tilted from perpendicular with respect to the light beam such that reflections are avoided. The analyzer may have a wedge shape such that one surface mates level with an optical fiber and the opposing surface is tilted to prevent reflections. Alternatively, a wedge-shaped block may be located between the analyzer and the optical fiber.

The electrochromic optical attenuator comprises a semi-transparent electrochromic device, and a plurality of electrodes configured to conduct electricity to the electrochromic device such that the transparency of the electrochromic device will be affected by an amount proportional to the magnitude of the electricity applied to the plurality of electrodes. The intensity of the light signal transmitted through the electrochromic device is affected by an amount proportional to the magnitude of the electricity applied to the plurality of electrodes. The electrochromic optical attenuator also includes at least one polarizing element having an optical polarization axis, wherein the polarizing element transmits a portion of the light signal proportional to the angular difference between the optical polarization axis of the light signal and that of the polarizing element. In one embodiment, the electrochromic optical attenuator is employed in a laser package that includes a laser, a pair of polarizing elements, and a faraday rotator.

摘要： A prosthetic retina for implantation in an eye having a defective retina is formed from an array of nanowires having a predetermined spatial distribution, density, size and shape implanted in close proximity to the retina. An electrical conductor is formed at a first end of all nanowires in the array of nanowires and placed in contact with a bias source which biases the array. A plurality of electrodes is located on a second end of each of one nanowire or a bundle of nanowires in the array. Each nanowire produces a photocurrent at a corresponding electrode in response to detection of light impinging on the array of nanowires and the photocurrent stimulates one or more neurons adapted for visual perception. In the preferred embodiment, the predetermined spatial distribution mimics a distribution of rods and cones in a normal eye.
