Abstract: A semiconductor material emitting device is positioned such that its output flux impinges on a substrate at a non-perpendicular angle, so as to grow a first epilayer which is linearly graded in the direction perpendicular to the growth direction. The linear grading can be arranged such that, for example, each row of pixels has a different cutoff wavelength, thereby making it possible to provide a spectroscopic FPA without the use of filters. The non-perpendicular angle and/or the flux intensity can be adjusted to achieve a desired compositional grading. A spectral ellipsometer may be used to monitor the composition of the epilayer during the fabrication process, and to control the intensity of the flux.

Abstract: A testing device for bottom-emitting or bottom-detecting optical devices may comprise a support structure to support a lower transparent chuck and an upper transparent chuck that includes a set of vacuum holes. In some implementations, a vacuum may be formed in a space between the lower transparent chuck and the upper transparent chuck when a vacuum pump is applied to an opening in a sidewall of the support structure. For example, the vacuum may create suction to cause an optical device under test to be mechanically secured on a top surface of the upper transparent chuck. The testing device may further comprise a photodetector disposed below the lower transparent chuck to detect light that travels through the upper transparent chuck and the lower transparent chuck when one or more probes complete an electrical path that causes the optical device under test to emit the light.

In examples, a regex-based pattern recognition platform may receive a dataset and determine whether at least a first regex pattern and a second regex pattern can be identified. The occurrences of the first and second regex patterns and the frequency of those occurrences may reveal something about the dataset itself or any patterns contained therein.
