    摘要: The thermally switched reflective optical shutter is a self-regulating “switchable mirror” device that reflects up to 100% of incident radiant energy above a threshold temperature, and reflects up to 50% of incident radiant energy below a threshold temperature. Control over the flow of radiant energy occurs independently of the thermal conductivity or insulating value of the device, and may or may not preserve the image and color properties of incoming visible light. The device can be used as a construction material to efficiently regulate the internal temperature and illumination of buildings, vehicles, and other structures without the need for an external power supply or operator signals. The device has unique aesthetic optical properties that are not found in traditional windows, skylights, stained glass, light fixtures, glass blocks, bricks, or walls. The device can be tailored to transmit sufficient visible light to see through in both the transparent and reflective states, while still providing significant control over the total energy transmission across the device.

    摘要: The present invention relates to a temporal depolarization assembly. The depolarization assembly operates to produce light that, over some period of time, is depolarized. The depolarization assembly includes first and second variable retarders. The variable retarders are operated to produce a retardance that varies in time. In addition, the modulator axis of a first one of the variable retarders is held at an angle to the modulator axis of the second one of the variable retarders. The frequency at which the retardance of the variable retarders varies is selected to be some fraction of the integration time of a sensor associated with the polarization assembly.

    摘要: A polarization conversion device converts a polarization state of a light which is input to a first waveguide, that is, TE/TM mode of the light, to output it from the first waveguide. The polarization conversion device includes: a mode converter that performs the inter-conversion of TE/TM modes of the light which is input to the first waveguide; and a polarization separator that receives the light passed through the mode converter and separates the received light into a first light, TE/TM of which mode has been converted by the mode converter and a second light, TE/TM of which mode has not been converted, to output the first light to the first waveguide.

    摘要: Techniques and devices for depolarizing light and producing a variable differential group delays in optical signals. In one implementation, an input optical beam is split into first and second beams with orthogonal polarizations. One or two optical reflectors are then used to cause the first and second optical beams to undergo different optical path lengths before they are recombined into a single output beam. An adjustment mechanism may used implemented to adjust the difference in the optical path lengths of the first and second beams to produce a variable DGD. When the depolarization of light is desired, the difference in the optical path lengths of the first and second beams is set to be greater than the coherence length of the input optical beam.

    摘要: A polarization scrambler, and associated method for polarization scrambling, is provided wherein light is passed through a time-variant retarder. At least after upstream connection or downstream connection of a time-invariant retarder, this time-variant retarder may be represented as a retarder with eigen modes which are uniformly distributed on the Poincaré sphere and with a delay of 5π/6. An exemplary embodiment contains only two electro-optical wave plates, which are actuated by alternating signals containing harmonics. The polarization scrambler which is produced is independent of the input polarization of the light and can be used in devices for detection of polarization mode dispersion.

    摘要: Apparatus and an accompanying method for an optical scrambler and particularly one that provides randomly scrambled states of polarization (SOPs) in an optical fiber. Specifically, polarization independence is achieved by wrapping a single optical fiber around each tube in a cascade of separate piezoelectric tubes, with random amounts of fixed birefringence separating each tube, where each tube is then separately excited on a time-varying basis. The tubes are arranged in two groups. Each tube in the first group is separately excited by combined frequency/amplitude modulation with illustratively different modulating frequencies and amplitudes, and in the second group is excited at illustratively a constant frequency and voltage. Time-varying birefringence produced by each tube perturbs an initial SOP of the light provided by that tube from its original pseudo-stationary position as depicted on a poincaré sphere.
