  • Patent number: 10684415
    Abstract: Roughly described, an integrated optical device includes both a PLC chip and an attached SiPh chip. The PLC chip has a PLC waveguide which terminates at an end facet. The SiPh chip has a SiPh waveguide which includes a Bragg grating which diffracts light from the SiPh waveguide toward the PLC chip. The PLC chip also has a turning mirror to reflect light emitted from the Bragg grating onto the end facet of the PLC waveguide. The Bragg grating is designed to direct light emitted from the Bragg grating into the end facet of the PLC waveguide so that after reflecting off the turning mirror the light focuses within one Rayleigh distance of the end facet of the PLC chip.

  • Patent number: 10684531
    Abstract: A light beam can be steered using a non-mechanical beam steerer structure. For example, a combination of sub-aperture and full-aperture beam steering structures can be used (e.g., corresponding to regions of controlled variation in an index of refraction). The sub-aperture elements can include tapered structures defining a saw-tooth or triangular footprint in the plane in which the in-plane steering is performed. Respective rows of sub-aperture tapered structures can be configured to controllably steer the light beam in the first in-plane direction, wherein at least one row of sub-aperture tapered structures defines a first base region edge that is tipped at a first specified in-plane angle relative to a second base region edge defined by another row. Use of the tipped configuration can simplify a configuration of the beam steerer structure, such as allowing a configuration lacking a compensation plate at the input.

  • Patent number: 10649246
    Abstract: A dielectric thin film-applied substrate that suppresses occurrence of cracks when the film thickness of the lithium niobate film is equal to or larger than 1 ?m.

The dielectric thin film has a twin crystal structure including first and second crystals 180° apart, centered on the c-axis. In pole figure measurement by X-ray diffraction, the ratio between a first diffraction intensity corresponding to the first crystal and a second diffraction intensity corresponding to the second crystal is equal to or higher than 0.5 and equal to or lower than 2.0, which alleviates distortions accumulated inside the lithium niobate film and supresses occurrences of cracks accompanying increases in the film thickness.
