Abstract: A transflective display panel and a display apparatus using the same are provided. The display panel includes a plurality of pixels arranged in a matrix. Each of the pixels includes a plurality of subpixels, and each subpixel within a pixel outputs a different color of light. In addition, each of the subpixels includes a transflective mode region which has a reflection mode region with a diffraction grating and a transmission mode region; a liquid crystal layer which adjusts a transmittance of incident light through electric control; and a sub color filter which transmits light within a wavelength band of the incident light. Because the display panel includes the reflection mode region where the diffraction grating is formed, it can display a high-quality image with good white balance, even while outdoors or under bright illumination.

Abstract: Simultaneous amplitude and phase control of ultrafast laser pulses using a single, linear (one-dimensional) liquid crystal spatial light modulator is described. Amplitude shaping is accomplished by writing a high-frequency phase grating having a spatial period much smaller than the spectral focus (over-sampling), onto the modulator, and diffracting away selected frequencies in a controllable manner, while spectral phase control is imparted by adding an appropriate slow phase bias to the modulator. The close pixel spacing, large number of pixels, and small footprint of the reflective spatial light modulator employed with an angular wavelength dispersive element in a folded Martinez stretcher, enables a simple and compact apparatus to be achieved. The high reflectivity of the spatial light modulator results in a highly efficient pulse shaper when either a prism or diffractive grating is used for the angular dispersive element. The use of a transmissive spatial light modulator in an unfolded Martinez stretcher configuration is also described.

Abstract: A distributed optical structure comprises a set of diffractive elements. Individual diffractive element transfer functions collectively yield an overall transfer function between entrance and exit ports. Diffractive elements are defined relative to virtual contours and include diffracting region(s) altered to diffract, reflect, and/or scatter incident optical fields (altered index, surface, etc). Element and/or overall set transfer functions (amplitude and/or phase) are determined by: longitudinal and/or angular displacement of diffracting region(s) relative to a virtual contour (facet-displacement grayscale); longitudinal displacement of diffractive elements relative to a virtual contour (element-displacement grayscale); and/or virtual contour(s) lacking a diffractive element (proportional-line-density gray scale). Optical elements may be configured: as planar or channel waveguides, with curvilinear diffracting segments; to support three-dimensional propagation with surface areal diffracting segments; as a diffraction grating, with grating groove or line segments.
