摘要： A reflective optical data modulator includes a layer of optical material, a front partial optical reflector on a major surface of the layer of optical material, a back optical reflector, and at least two electrodes. The back optical reflector is at or near a portion of a second surface of the layer of optical material and faces the front partial optical reflector. The at least two, electrodes are located to enable application of a voltage across a portion of the layer of optical material. The layer of optical material has an optical absorption dependent on the voltage applied across the electrodes. The front partial optical reflector is an unburied layer structure.

摘要： In a radio frequency (RF)-photonic arbitrary waveform generator (AWG), an optical carrier signal is phase-modulated using an arbitrary waveform optical phase generator (AWPOG), which may include, e.g., sequential optical phase modulators. The phase-modulated optical signal is combined with a version of the optical carrier signal to yield an optical waveform, whose amplitude varies with a phase shift introduced by the AWPOG to the optical carrier signal. By manipulating electrical inputs to the AWPOG which control the phase shift, the optical waveform can be arbitrary shaped. The optical waveform may then be converted to an electrical waveform having a radio frequency.

摘要： An optical receiver has a monolithically integrated electrical and optical circuit that includes a substrate with a planar surface. Along the planar surface, the monolithically integrated electrical and optical circuit has an optical hybrid, one or more variable optical attenuators, and photodetectors. The optical hybrid is connected to receive light beams, to interfere light of said received light beams with a plurality of relative phases and to output said interfered light via optical outputs thereof. Each of the one or more variable optical attenuators connects between a corresponding one of the optical outputs and a corresponding one of the photodetectors.

摘要： The present invention discloses a two-step CMP method and employed polishing compositions. In the first step, a first polishing slurry is provided to selectively polish the Al-alloy layer. Next, a second polishing slurry is provided to selectively polish the barrier layer. Accordingly, undesired surface non-planarity after the CMP process, such as metal dishing and corrosion of dielectric layers with complicated pattern geometry, can be avoided, and thus the planarization of wafer surfaces can be achieved.
