Abstract
Packaging and interconnect systems for edge-emitting light modulators are disclosed. Embodiments address the challenge of integrating many edge-emitting modulators such as surface acoustic wave (SAW) modulators together in a single light field generator system. In one example, a proposed light field generator system includes a stack of projector modules and a mounting block having slots. The projector modules preferably have a printed circuit board (PCB) form factor that enables the slots of the mounting block to receive and hold the modules. Each module includes a module board and one or more SAW substrates carried by the module board, and an array of SAW modulators are formed/fabricated within each substrate. Proposed substrate fabrication techniques provide wiring and routing of RF and optical signals to the SAW modulators within each substrate to achieve a density of light modulators suitable for practical application to light field projection systems.
