    Abstract: A substantially planar waveguide for dynamically controlling the out-of-plane angle at which a light beam exits the waveguide. Generally, liquid crystal materials may be disposed within a waveguide in a cladding proximate or adjacent to a core layer of the waveguide. In one example, the waveguide may contain one or more taper regions such that the light beam exits the waveguide and propagates out-of-the-plane of the waveguide into an out-coupling medium at a propagation angle. In one example, the waveguide may contain one or more electrodes onto which one or more voltages may be applied. The magnitude of the propagation angle may be electronically controlled by altered by controlling or altering the magnitude of the one or more applied voltages.

    Abstract: Ring modulators based on interdigitated junctions may be driven in full or partial standing wave mode and, active regions (providing the modulation) and light-absorptive regions (e.g. providing electrical conduction) are placed in a pattern inside a resonant cavity in order to match the maxima and minima of the optical field, respectively. The pattern may be periodic to match the periodicity of a typical electromagnetic field which is periodic with the wavelength. It may also be aperiodic in the case that the cross-section or materials are engineered along the direction of propagation such that the propagation constant (and thus wavelength, i.e. optical wave “local periodicity”) change along the propagation direction.

    Abstract: The present invention is based on a two-dimensional photonic crystal in which are inserted, in a controlled manner, defects that originate the waveguides and the resonant cavity that integrate the device. Its main function is to provide the control of the passage of an electromagnetic signal over a communications channel, blocking (state off) or allowing (state on) the passage of the signal. It also has the function of changing the propagation direction of an electromagnetic signal by an angle of 60 degrees, offering greater flexibility in the design of integrated optical systems. The operating principle of the device is associated with the excitation of dipole modes in the resonant cavity, which is based on a magneto-optical material. When the switch is under the influence of an external DC magnetic field H0, a rotating dipole mode excited in the cavity allows the passage of the input signal to the output (state on), whereas without the application of H0, a stationary dipole mode excited in the cavity, with the nodes aligned to the output waveguide, prevents the passage of the input signal to the output (state off).

    Abstract: Systems and methods are presented for modulating a beam of radiation, such that the modulated beam exhibits substantially null residual amplitude modulation (RAM). An electro-optical modulator is presented that includes a waveguide, a first region associated with the waveguide and a second region associated with the waveguide. The waveguide is designed to guide a beam of radiation. A first electric potential applied to the first region causes a first modulation to the beam of radiation while a second electric potential applied to the second region causes a second modulation to the beam of radiation. The first modulation combined with the second modulation provides substantially null residual amplitude modulation of the beam of radiation.

    Abstract: Methods and systems for a low-parasitic silicon high-speed phase modulator are disclosed and may include fabricating an optical phase modulator that comprises a PN junction waveguide formed in a silicon layer, wherein the silicon layer may be on an oxide layer and the oxide layer may be on a silicon substrate. The PN junction waveguide may have p-doped and n-doped regions on opposite sides along a length of the PN junction waveguide, and portions of the p-doped and n-doped regions may be removed. Contacts may be formed on remaining portions of the p-doped and n-doped regions. Portions of the p-doped and n-doped regions may be removed symmetrically about the PN junction waveguide. Portions of the p-doped and n-doped regions may be removed in a staggered fashion along the length of the PN junction waveguide. Etch transition features may be removed along the p-doped and n-doped regions.
