Abstract: An optical transmitter comprises a directly coupled MZ interferometer and driver circuit. The MZ interferometer comprises a pair of differentially driven MZ electrodes configured to impart RF signals to light travelling through respective arms of the interferometer, and to receive DC bias as a positive voltage via lower n-type cladding of the MZ interferometer. The lower n-type cladding is at a different positive DC potential to an upper plane RF ground of the MZ interferometer, but the lower n-type cladding and the upper plane RF ground have similar AC potential. The MZ interferometer also comprises a pair of resistors in series configured to provide differential RF termination of the MZ electrodes; and a capacitive coupling between a virtual ground formed at a centre point between the pair of resistors and an RF ground configured to provide common-mode RF termination. The DC supply for the driver circuit is applied to the centre point of the RF termination.

Abstract: Techniques are provided to encode and decode image data comprising a tone mapped (TM) image with HDR reconstruction data in the form of luminance ratios and color residual values. In an example embodiment, luminance ratio values and residual values in color channels of a color space are generated on an individual pixel basis based on a high dynamic range (HDR) image and a derivative tone-mapped (TM) image that comprises one or more color alterations that would not be recoverable from the TM image with a luminance ratio image. The TM image with HDR reconstruction data derived from the luminance ratio values and the color-channel residual values may be outputted in an image file to a downstream device, for example, for decoding, rendering, and/or storing. The image file may be decoded to generate a restored HDR image free of the color alterations.

Abstract: The Application Source Code Reuse Apparatuses, Methods and Systems (“ACR”) transforms compilation request inputs via ACR components into compilation response outputs. A compilation request datastructure that specifies an application identifier is obtained. A first source code branch associated with the application identifier is pulled from a source code repository. A second source code branch associated with the application identifier is rebased using the first source code branch. A first transformation file in the second source code branch is selected. The first transformation file is written in a first programming language and includes a first set of annotations that specify how to modify the first transformation file into a compilable file in the first programming language. The first transformation file is transformed, in accordance with the first set of annotations, into a compilable file in the first programming language. A content package is generated using the transformed first transformation file.

Abstract: A provider network may implement resource management and billing for logical and physical availability zones. Consolidated billing techniques may be applied to the aggregate usage of multiple linked user accounts. A billing setting may indicate whether consolidated billing is performed according to resource consumption in logical availability zones or physical availability zones. Mappings to physical availability zones may be provided to linked user accounts so that computing resources may be consumed according to either logical or physical availability zones. Capacity reservations for computing resources for a particular physical availability zone may be made available to each of the linked user accounts for consumption.
