摘要： A ferroelectric liquid crystal-based light valve [100] comprising a light input [106], a light output [108], a polarizing beam splitter [119], a reflective spatial light modulator [25] and a switchable half-wave plate [102]. Light polarized parallel to a first direction is received through the light input. Light from the light input and reflected by the spatial light modulator is output from the light output. The reflective spatial light modulator is structured as a quarter-wave plate and has a principal axis that switches through an angle φ. The polarizing beam splitter has orthogonal directions of maximum transmissivity and maximum reflectivity, one of which is parallel to the first direction. The polarizing beam splitter is located and aligned relative to the light input, the light output, and the spatial light modulator to transmit or reflect the light from the light input towards the spatial light modulator, and to reflect or transmit, respectively, towards the light output the light reflected by the spatial light modulator and having a direction of polarization substantially orthogonal to the first direction. The switchable half-wave plate is located between the beam splitter and the spatial light modulator, is structured as a half-wave plate and has a principal axis that switches through an angle θ, substantially equal to φ/2. The switchable half-wave plate inverts the sense of the light valve during the balance period of each display period to enable the light valve to generate a positive image, and therefore be illuminated, during the balance period in addition to during the illumination period.

摘要： A low noise multimode VCSEL (300) which can be used to transmit data reliably on multimode optical media at data rates up to and exceeding 1 gigabit per second with bit error rates less than 1 x 10 -9 errors/bit, has a conventional multimode laser structure where optimal mirror reflectivity is increased to a point where the output power is less than half the maximum output power. Preferably, the reflectivity of the first and second mirror regions (302,308) of the multimode laser is high, typically greater than 99.5%.

摘要： A composition for use in constructing a photosensitive film (10) for recording an image. The composition comprises first, second, and third particles (12-14). Each particle type comprises a crystalline base material having a trap dopant and a color dopant deposited therein. Each color dopant has a different spectral sensitivity. In one embodiment, each of the trap dopants has a different activation energy for releasing electrons traps therein into the conduction band of the crystalline base material. In another embodiment, the base material is applied as a thin film and the dopant atoms (101-103) deposited therein in a pattern provide the equivalent of the three particle types (100-112).
