摘要： A display device for displaying 3D holographic images has multiple pixels, each having a set of coupled optical resonators. The optical paths of the coupled optical resonators can be adjusted to impart a desired phase shift to light passing through the coupled optical resonators. The transmission amplitude and phase of each pixel of the display can be dynamically and individually adjusted for displaying 3D holographic images.

摘要： An optoelectronic memory cell has a transparent top electrode, a photoactive layer, a latching layer, and a bottom electrode. The photoactive layer absorbs photons transmitted through the top electrode and generates charge carriers. During light exposure, the latching layer changes its resistance under an applied electric field in response to the generation of charge carriers in the photoactive layer.

In accordance with one embodiment, the optical modulator comprises a waveguide for guiding an optical signal, and further comprises a ring resonator disposed in evanescent communication with the waveguide for at least one predetermined wavelength of the optical signal. The optical modulator further comprises a semiconductor pnpn junction structure that is at least partially coextensive with at least a portion of a resonant light path of the ring resonator.

The electrical control signal controls a free carrier population in the resonant light path where coextensive with the pnpn junction structure. A resonance condition of the ring resonator at the predetermined wavelength is thereby controlled by the electrical control signal, and the optical signal is thereby modulated according to the electrical control signal.
