Abstract: A self-lit display panel includes a photonic integrated circuit payer including an array of waveguides and an array of out-couplers for out-coupling portions of the illuminating light through pixels of the panel. The self-lit display panel may include a transparent electronic circuitry layer backlit by the photonic integrated circuit layer; the two layers may be on a same substrate or on opposed substrates defining a cell filled with an electro-active material. The configuration allows for chief ray engineering, zonal illuminating, and separate illumination with red, green, and blue illuminating light.

Abstract: The present disclosure relates to a method comprising the following steps: a) forming a waveguide from a first material, the waveguide being configured to guide an optical signal; b) forming a layer made of a second material that is electrically conductive and transparent to a wavelength of the optical signal, steps a) and b) being implemented such that the layer made of the second material is in contact with at least one of the faces of the waveguide, or is separated from the at least one of the faces by a distance of less than half, preferably less than a quarter, of the wavelength of the optical signal. The application further relates to a phase modulator, in particular obtained by such a method.

Abstract: Methods and systems for a low-voltage integrated silicon high-speed modulator may include an optical modulator comprising first and second optical waveguides and two optical phase shifters, where each of the two optical phase shifters may comprise a p-n junction with a horizontal section and a vertical section and an optical signal is communicated to the first optical waveguide. A portion of the optical signal may then be coupled to the second optical waveguide. A phase of at least one optical signal in the waveguides may be modulated utilizing the optical phase shifters. A portion of the phase modulated optical signals may be coupled between the two waveguides, thereby generating two output signals from the modulator. A modulating signal may be applied to the phase shifters which may include a reverse bias.

Abstract: Embodiments of an optical modulator device are described. An example optical modulator includes a ridge laser configured to emit light, a ridge waveguide configured to transition between a transparent state and an absorbing state, and a waveguide tap formed between the ridge laser and the ridge waveguide. The waveguide tap is configured to optically couple a fraction of light generated in the ridge laser to the ridge waveguide. In the transparent state of the ridge waveguide, the ridge waveguide is configured to output the fraction of light for interference with light emitted from the ridge laser. In the absorbing state of the ridge waveguide, the ridge waveguide is configured to absorb the fraction of light. Depending upon whether the fraction of light is output from the ridge waveguide for interference, the output power of the laser seen at the far-field of the optical modulator can be modulated for data communications.
