  • Patent number: 10234686
    Abstract: In a near-eye optical display system comprising a waveguide and diffractive optical elements (DOEs) configured for in-coupling, exit pupil expansion, and out-coupling, a rainbow phenomenon manifested in the display may be removed or reduced using a polarizing filter at the front of the system so that real-world/stray light entering the system has a particular polarization state, for example TM-polarized. The polarizing filter is utilized in conjunction with a downstream out-coupling DOE that includes diffractive grating structures that are configured to enable sensitivity to an opposite polarization state, for example TE-polarized. An imager is configured to produce virtual-world images that also have a TE-polarized state. The polarization-sensitive out-coupling DOE diffracts the TE-polarized imaging beam out of the grating for display while the TM-polarized light from the real world and/or stray light passes through the grating without diffraction and thus cannot contribute to rainbows in the display.

    Abstract: The invention relates to a method for checking the correct assembly of a device consisting of a frame and of two corrective ophthalmic lenses. The main feature of a method according to the invention is that it includes the following steps: an initial step of determining at least one parameter which makes it possible to position the lenses in the frame relative to the face; a subsequent step of acquiring at least one image of the face of said wearer with said device, which shows centering and horizontal level marks; a step of comparing said at least one parameter determined during said initial step with the corresponding parameter deduced from said at least one image; and a step of making a decision regarding the correct assembly of the device.

  • Patent number: 10234701
    Abstract: In the Waveguide Array Modulator (WAM) a single electrical signal drives an array of waveguide optical modulators, creating multiple modulated output signals that can be combined to provide a higher output power than from a single waveguide based modulator, enabling a higher dynamic range system. Alternatively, using a WAM in which different waveguide optical modulators are designed for different dynamic ranges, e.g. one highly efficient modulator for low level signals and one low efficiency but linear modulator for high level signals, the WAM based system can provide a higher dynamic range than from a single waveguide based modulator. Various WAM based systems for different applications are included.

  • Patent number: 10234702
    Abstract: In an optical device, a ring-resonator modulator, having an adjustable resonance (center) wavelength, receives an optical signal that includes a carrier wavelength from an input-output optical waveguide. Then, a monitoring mechanism monitors a performance metric (such as an average power or a signal swing) of a monitor optical signal from the ring-resonator modulator. Moreover, control logic in the optical device adjusts the resonance wavelength based on the monitored performance metric so that the resonance wavelength is locked to the carrier wavelength. In particular, the control logic may apply a change to an adjustment signal that is provided to the ring-resonator modulator. If the change increases the performance metric, the control logic may continue to modify the resonance wavelength. Otherwise, the control logic may modify the resonance wavelength by applying one or more changes, having an opposite sign to the change, to the adjustment signal.

  • Patent number: 10234703
    Abstract: An optical modulator uses an optoelectronic phase comparator configured to provide, in the form of an electrical signal, a measure of a phase difference between two optical waves. The phase comparator includes an optical directional coupler having two coupled channels respectively defining two optical inputs for receiving the two optical waves to be compared. Two photodiodes are configured to respectively receive the optical output powers of the two channels of the directional coupler. An electrical circuit is configured to supply, as a measure of the optical phase shift, an electrical signal proportional to the difference between the electrical signals produced by the two photodiodes.

  • Patent number: 10234704
    Abstract: An optical module includes: an optical modulator, a superimposing unit, an offset adding unit, a detector, and a bias controller. The optical modulator includes a first modulator to generate a first optical signal, a second modulator to generate a second optical signal and a phase shifter to provide a specified phase difference between the first optical signal and the second optical signal so as to generate a modulated optical signal. The superimposing unit superimposes a low frequency signal on a DC bias of the first modulator. The offset adding unit adds an offset to a DC bias of the second modulator. The detector detects a low frequency component from output light of the optical modulator. The bias controller controls a DC bias that is applied to the phase shifter based on the low frequency component detected by the detector.

  • Patent number: 10234705
    Abstract: A driver configuration for driving a Mach-Zehnder modulator (MZM) includes a first driver supplied by a first voltage and a second voltage and configured to provide a first two complimentary outputs respectively to a first N-electrode of a first branch of the MZM and a second N-electrode of a second branch of the MZM. Additionally, the driver configuration includes a second driver supplied by a third voltage and a fourth voltage and configured to provide a second two complimentary outputs respectively to a first P-electrode of the first branch and a second P-electrode of the second branch. The driver configuration sets a difference between the third voltage and the fourth voltage equal to a difference between the first voltage and the second voltage to provide a same peak-to-peak differential swing for modulating light wave through each transmission line and output a modulated light with twice of the peak-to-peak differential swing.
