  • Publication number: 20170146740
    Abstract: Conventional approaches to integrating waveguides within standard electronic processes typically involve using a dielectric layer, such as polysilicon, single-crystalline silicon, or silicon nitride, within the in-foundry process or depositing and patterning a dielectric layer in the backend as a post-foundry process. In the present approach, the back-end of the silicon handle is etched away after in-foundry processing to expose voids or trenches defined using standard in-foundry processing (e.g., complementary metal-oxide-semiconductor (CMOS) processing). Depositing dielectric material into a void or trench yields an optical waveguide integrated within the front-end of the wafer. For example, a shallow trench isolation (STI) layer formed in-foundry may serve as a high-resolution patterning waveguide template in a damascene process within the front end of a die or wafer.

  • Publication number: 20170146742
    Abstract: In a waveguide device, unnecessary optical power is appropriately terminated. According to an embodiment of the present invention, the waveguide device has a termination structure filled with a light blocking material to terminate light from a waveguide end. In the termination structure, a cladding and a core are removed to form a groove on an optical waveguide. The groove is filled with a material (light blocking material) that attenuates the intensity of light. Thus, light input to the termination structure is attenuated by the light blocking material, suppressing crosstalk which possibly effects on other optical devices. Thus, such a termination structure can restrain crosstalk occurred in optical devices integrated in the same substrate and can also suppress crosstalk which possibly effects on any other optical device connected directly to the substrate.

  • Publication number: 20170146780
    Abstract: A surgical stereoscopic observation apparatus includes an objective optical system having an optical axis and emits two focusing beams in parallel with the optical axis toward the objective optical system. If a focal point of the objective optical system agrees with a surgical field, the two focusing beams converge to a single spot on the surgical field, and if disagrees with the surgical field, form two spots on the surgical field. According to the state of the spots, it is possible to quickly determine with naked eye or on a monitor whether or not the focal point is on the surgical field.

    Abstract: A method for scanning a sample using an electrically or electronically controllable microscope includes performing a continuous scanning of the sample so as to repeatedly generate a plurality of images of the sample, each of the plurality of images corresponding to a different time, the microscope being controlled via a control computer during the scanning. The plurality of images are analyzed using at least one second computer connected via a network, wherein the at least one second computer is configured to classify each of the plurality of images as one of interesting and non-interesting while the continuous scanning of the sample with the microscope continues. The continuous scanning of the sample is automatically influenced based on the classifying of the images performed by the at least one second computer.

    Abstract: A microscope that makes it possible to acquire a hyperspectral image with high data precision includes a light source, an illumination optical system, an image-forming optical system, an imaging unit, a spectroscope, a stage, a drive unit, and a control unit. The illumination optical system converges, at a converging angle ?, illuminating light in a wavelength band included in the near-infrared region output from the light source, and emits the converged illuminating light onto the object being observed. The image-forming optical system forms an image based on transmitted and scattered light generated by the observed object by emission of the illuminating light onto the observed object. The sin ? is set to a value that does not exceed the numerical aperture of an objective lens that receives the transmitted and scattered light from the observed object.
