Summary of "Uniformly spaced λ/4-shifted Bragg grating array with wafer-scale CMOS-compatible process."

We report on an integrated λ/4-shifted Bragg grating array using a wafer-scale complementary metal-oxide semiconductor (CMOS) compatible process with silicon-nitride waveguides. A sidewall grating was used to simplify the fabrication process, and a sampled Bragg grating with equivalent phase-shift structure was employed to achieve an accurate λ/4 phase shift. A four-channel λ/4-shifted Bragg grating array with highly uniform channel spacing was demonstrated with a measured channel spacing variation below 10 pm (1.25 GHz). The high channel-spacing uniformity and the CMOS-compatibility of the demonstrated device hold promise for integrated distributed feedback laser arrays for various silicon photonic applications.

Medical and Biotech [MESH] Definitions

The simultaneous analysis of multiple samples of TISSUES or CELLS from BIOPSY or in vitro culture that have been arranged in an array format on slides or microchips.

Small uniformly-sized spherical particles, of micrometer dimensions, frequently labeled with radioisotopes or various reagents acting as tags or markers.

A genus of ciliate protozoa having a dorsoventrally flattened body with widely spaced rows of short bristle-like cilia on the dorsal surface.

Analytical technique for studying substances present at enzyme concentrations in single cells, in situ, by measuring light absorption. Light from a tungsten strip lamp or xenon arc dispersed by a grating monochromator illuminates the optical system of a microscope. The absorbance of light is measured (in nanometers) by comparing the difference between the image of the sample and a reference image.

A type of stress exerted uniformly in all directions. Its measure is the force exerted per unit area. (McGraw-Hill Dictionary of Scientific and Technical Terms, 6th ed)
