摘要： A switchable apochromatic polarization rotator is provided. A first fixed waveplate has a first principal axis fixed in a first orientation. A second fixed waveplate has a second principal axis fixed in a second orientation. First and second switchable waveplates have principal axes oriented such that broad spectral range electromagnetic radiation transmitted through all of the waveplates has a first rotated polarization, wherein, in response to one or more control signals applied to the switchable waveplates, the principal axes of the switchable waveplates rotate such that the electromagnetic radiation transmitted through all of the waveplates has a second rotated polarization. The switchable waveplates utilize ferroelectric liquid crystal material, nematic liquid crystal material, or be mechanically rotated to adjust for orientation of their principal axes. Utilizing waveplates as described may be used to tune for a desired spectral range and/or compensate for temperature dependencies.

摘要： An optical communication system may include a light transmission unit transmitting a light beam having a first polarization, a quarter waveplate to receive the light beam and to modify the light beam to have a second polarization, and a retroreflector to receive the light beam from the quarter waveplate and reflect the light beam to the quarter waveplate, which modifies the light beam to have a third polarization. The optical communication system may also include a half waveplate to modify the first polarization such that the first polarization is about 90 degrees rotated compared to the third polarization, and a polarizer to pass the light beam having the third polarization and to block most of the light beam having the first polarization.

摘要： Provided is a compact, high-speed deformable mirror for use with an adaptive optic. The mirror or wavefront correction device corrects and/or compensates for wavefront aberrations present in a wavefront received by the optics. The mirror includes a deformable membrane which may be made of a semiconductive, metallic or insulating material. Positioned in close proximity to a front surface of the membrane is a transparent conductor, which may be covered by a window having an anti-reflective coating. A plurality of electrostatic actuators is located in close proximity to a back surface of the membrane, the conductor and actuators separated by a gap of approximately 10 μm. In operation, a bias voltage is applied to the transparent conductor and an actuator voltage is applied to the plurality of actuators. The resultant voltage differential across the membrane defines the amount of membrane deformation, which in turn compensates for distortions in a subsequently reflected wavefront.
