    摘要： A test system includes an optical medium, a binding agent capable of capturing a target complex, and a light detector. The optical medium provides a light path, and the binding agent is positioned to hold the target complex in an evanescent field created by propagation of light along the light path. The complex interacts with the evanescent field and emits light that the detector positioned to detect. The optical medium and the detector can be included in an optical integrated circuit where detected light passes through the optical medium transverse to the direction of the light path.

    摘要： A ferroelectric liquid crystal-based switchable half-wave plate with improved alignment control, a ferroelectric liquid crystal-based light valve system with improved contrast control, and a method of improving contrast in a ferroelectric liquid crystal-based light valve system. The switchable half-wave plate with improved alignment control includes a layer of ferroelectric liquid crystal material sandwiched between a first transparent electrode and a second transparent electrode. The switchable half-wave plate also includes an electric field direction switching circuit configured to switch the electric field across the liquid crystal material between the forward direction and the reverse direction in response to a control signal. The switchable half-wave plate additionally includes an electric field magnitude control circuit to adjust the tilt angle in response to a signal received at a alignment control signal input. The ferroelectric liquid crystal-based light valve system according to the invention includes at least one ferroelectric liquid crystal-based spatial light modulator, an analyzer having a direction of minimum transmissivity, a ferroelectric liquid crystal-based switchable half-wave plate, and an adjustable voltage source. The voltage source is configured to adjust the magnitude of the electric field in at least one of the forward direction and reverse direction as the output voltage level is adjusted in response to a user interface or a light intensity sensor and a feedback circuit. The method of improving contrast in a ferroelectric light valve system according to the invention includes providing a ferroelectric liquid crystal-based spatial light modulator, an analyzer, a ferroelectric liquid crystal based switchable half-wave plate, and a video signal. In response to the video signal, a pixel electric field across each of the plurality of pixels is switched. Also an electric field across the switchable half-wave plate is periodically switched and the magnitude of the half-wave plate electric field is adjusted to align one of the first and the second half-wave plate director angles with one of the first and the second modulator director angles.

    摘要： An optical device capable of illuminating visual light with adjusting color temperature after fabrication is disclosed. The optical device includes a solid state light emitter and a phosphor layer, which is formed over the solid state light emitter. The solid state light emitter, which can be a light emitter diode (“LED”), converts electrical energy to blue light. The phosphor layer subsequently converts first light with a first wavelength to second light with a second wavelength. In one example, the first light is blue light while the second light is white light. A portion of the phosphor layer is adjusted after the phosphor layer is formed for adjusting color of the white light in accordance with color quality of the light detected by a light detector.
