摘要： A multi-pixel optical processing system includes a multi-pixel liquid crystal cell platform having a deposited metal gasket moisture barrier bonding two opposing substrates each having a spacer layer to accurately control cell gap thickness. A library of specialized pixel constructs is included that can be configured to yield predetermined optical functions at referential locations in the platform. A control system is provided utilizing a time division scheme that multiplexes temperature sensing and heating functions across an optional integrated active thermal element that may be integrated inside the liquid crystal platform. A calibration process characterizes the profile of the cell and generates a polynomial regression formula that provides the voltage drive output for all pixels in the platform based on the platform temperature and state of each pixel.

摘要： A twisted nematic liquid crystal variable optical attenuator is presented with one substrate that includes a integrated subwavelength nanostructured polarizer. The device may incorporate an integrated isolator whereby a substrate of the liquid crystal sandwich is formed from doped garnet to comprise a faraday rotator etched with a subwavelenth optical nanostructured polarizing grating and enabling the substrate to function as an isolator. The liquid crystal variable optical attenuator may include a deposited metal gasket moisture barrier bonding the opposing top and bottom substrates each having a spacer layer to accurately control cell gap thickness. The liquid crystal variable optical attenuator may also include an integrated thermal sensor and heater deposition layer sandwiched between or deposited on at least one or both opposing substrates.

摘要： A wavelength locker operates with a reference tunable liquid crystal filter having integrated photodetectors deposited on the front and backside of the liquid crystal cell to track power intensity of the accepted passband signal and its rejected signal compliment at a 50% power point where the two signals cross on the side of the filter transmission peak. The tunable filter is tuned by an offset wavelength from the laser wavelength such that 50% power is transmitted through the filter at the center wavelength of the laser. The wavelength locker may be configured with a liquid crystal tunable etalon or a liquid crystal tunable bandpass filter. A method for locking an optical signal to a desired frequency is also included and provides a substantially linear feedback signal computed by dividing the rejected signal power by the accepted signal power and passing it to laser transmitter to enable it to correct for frequency drift. Optional features of the present invention include an integrated thermal sensor and heater and temperature compensation control schemes.
