1.25 Gb/s transmitter for an adaptive redundant free-space optical interconnect

摘要

In order to provide a reliable optical line, the emitters and detectors within a free-space optical interconnect need to be aligned to each other within tight toelrances. Typical methods to achieve this alignment involve the use of precision optomechanics or active steering elements. An alternative approach to the alignment problem is to use spatial redundancy. One way to accomplish this is by increasing the number of possible optical links and using only a subset of those links to provide reliable high-speed channels. This paper presents the design and testing of a high speed transmiter chip developed for an adaptive reducdant optical interconnect system. Optoelectronic design and device packaging will also be described.
