  • Publication number: 20180175587
    Abstract: An array of monolithic wavelength division multiplexing (WDM) vertical cavity surface emitting lasers (VCSELs) with spatially varying gain peak and Fabry Perot wavelength is provided. Each VCSEL includes a lower distributed Bragg reflector (DBR), a Fabry Perot tuning/current spreading layer, and a structure comprising a multiple quantum well (MQW) layer sandwiched between a lower separate confinement heterostructure (SCH) layer and an upper SCH layer. The structure is sandwiched between the DBR and the Fabry Perot tuning/current spreading layer. Each MQW experiences a different amount of quantum well intermixing and concomitantly a different wavelength shift. Each VCSEL further includes a top mirror on the Fabry Perot tuning/current spreading layer. A method is also provided for manufacturing the array.

  • Patent number: 9995876
    Abstract: Compact photonics platforms and methods of forming the same are provided. An example of a compact photonics platform includes a layered structure having an active region along a longitudinal axis, a facet having an angle no less than a critical angle formed at least one longitudinal end of the active region, and a waveguide having at least one grating coupler positioned in alignment with the angled facet to couple light out to or in from the waveguide.

  • Publication number: 20180157552
    Abstract: Examples associated with data validation are disclosed. One example includes a sensor attribute data store having information describing attributes of a set of distributed sensors. A pattern data store stores information describing patterns indicating anomalous sensor activity. A data aggregation module flags data received from a tested sensor as anomalous data when the anomalous data exceeds a variance level described by an attribute of the tested sensor. A data validation module validates the anomalous data by comparing the anomalous data to the patterns indicating anomalous sensor activity. A learning module updates the pattern indicating anomalous sensor activity based on a result received from the validation logic after the validation logic validates data received from the tested sensor.

  • Publication number: 20180154632
    Abstract: In an embodiment, a printhead includes a fluidic die molded into a moldable material. The die has a front surface exposed outside the moldable material to dispense fluid and an opposing back surface covered by the moldable material except at a channel in the moldable material through which fluid may pass directly to the back surface. The die has a first bond pad on the front surface surrounded by a first dam to prevent the moldable material from contacting the first bond pad.

  • Publication number: 20180154663
    Abstract: Examples associated with printer configuration are disclosed. One example includes printing, using a printer, a first portion of a test patch in a first print direction. A second portion of the test patch is printed in a second print direction. The second portion is printed at a first offset from the first portion. A first portion of a second test patch is printed in the first print direction, and a second portion of the second test patch is printed in the second print direction at a second offset from the first portion of the second test patch. The printer is configured to print in the second print direction using one of the first offset and the second offset based on a selection between the first test patch and the second test patch.

  • Publication number: 20180154647
    Abstract: A printing fluid circulation system is described. The system comprises first and second reservoirs, an outlet to supply printing fluid to a fluid inlet of a printhead, an inlet to receive printing fluid from a fluid outlet of the printhead, and a supply system. The supply system is to operate in a first mode to concurrently supply printing fluid from the first reservoir to the outlet and from the inlet to the second reservoir, and in a second mode to concurrently supply printing fluid from the second reservoir to the outlet and from the inlet to the first reservoir.

  • Publication number: 20180154654
    Abstract: Certain examples described herein relate to evaluating print quality. In these examples, a check image is printed at a first print quality in accordance with test image data for at least one test image, and a reference image is printed at a second print quality with reference image data corresponding to the one or more test images modified to simulate one or more print defects. A comparison of the printed reference image and the printed check image allows evaluation of a quality level for the printed check image.

  • Publication number: 20180154576
    Abstract: Examples include a printhead comprising a plurality of nozzles for ejecting printing material drops. Examples include at least one emission device positioned proximate the printhead, where the at least one emission device is to emit energy to thereby expose ejected printing material drops to emitted energy to change at least one material property of ejected printing material drops in-flight.
