摘要： An optical device in which crosstalk due to scattering is reduced includes an optical port array having at least one optical input for receiving an optical beam and at least one optical output. The input and outputs extend along a common axis. A dispersion element receives the optical beam from the optical input and spatially separates the optical beam into a plurality of wavelength components. A focusing element focuses the plurality of wavelength components and a programmable optical phase modulator receives the focused plurality of wavelength components. The modulator is configured to steer the wavelength components to a selected one of the optical outputs. The programmable optical phase modulator is oriented with respect to the optical port array so that an axis along which the optical beam is steered is non-coincident with the common axis along which the input and outputs extend.

摘要： 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).

摘要： Embodiments are provided for an apparatus and method for differential thermal optical switch control. The optical switch is operated based on the interferometric principle by modifying the optical phase between waves propagating in waveguides via refractive index change in the waveguides using the thermo-optic effect. A heat pump designed as part of the optical switch is used to generate a temperature difference across the waveguides based on the thermo-electric effect. The thermo-electric effect is obtained using thermo-electric material or elements, also referred to as Peltier elements. An embodiment apparatus includes a dielectric base, a pair of waveguides extended in parallel on the dielectric base, and on the dielectric base a thermo-electric material in contact with the pair of waveguides. Additionally, a pair of electrodes extended, on the thermo-electric material, next to and along the length of the waveguides.

摘要： Thermal control devices, photonic systems and methods of stabilizing a temperature of a photonic system are provided. A thermal control device thermally coupled to a substrate includes a waveguide for receiving light, an absorption element optically coupled to the waveguide for converting the received light to heat and an optical filter. The optical filter is optically coupled to the waveguide and thermally coupled to the absorption element. An operating point of the optical filter is tuned responsive to the heat from the absorption element. When the operating point is less than a predetermined temperature, the received light is passed to the absorption element via the optical filter. When the operating point is greater than or equal to the predetermined temperature, the received light is transmitted out of the thermal control device via the optical filter, without being passed to the absorption element.
