Abstract: A semiconductor chip has at least two DFB etched facet laser cavities with one set of facets with AR coatings and a second set of etched facets with HR coatings that have a different relative position with respect to the gratings. This creates a difference in the phase between each of the etched facets and the gratings which changes the operational characteristics of the two laser cavities such that at least one of the lasers provides acceptable performance. As a result, the two cavity arrangement greatly improves the yield of the fabricated chips.

Abstract translation: 半导体芯片具有至少两个具有AR涂层的DFB刻蚀小面激光腔，其具有一组具有AR涂层的刻面，以及具有HR涂层的第二组蚀刻刻面，其具有相对于光栅的不同相对位置。 这产生了每个蚀刻面和光栅之间的相位的差异，其改变了两个激光腔的操作特性，使得至少一个激光器提供可接受的性能。 结果，两个腔体布置大大地提高了所制造的芯片的产量。

Abstract: A method for increasing the rate of transfer of web page data files having embedded data files between users of an Internet service and an Internet server. The method is implemented from a set of instructions read by a computer from a diskette. The executed method assigns a first communication channel of the computer to transfer a first data file between the server and the user. The data file is checked for the identity of embedded files, and the identity and address of the embedded files are stored in a table. The embedded files are thereafter transferred through the first communication channel and a second communication channel following transfer of the first data file. In the event that a data transfer of a file becomes stalled, an additional channel is assigned to simultaneously transfer the stalled file with the channel carrying the stalled file.
