High Performance Controller with “Hybrid” Alignment System
A solution is demonstrated with PI’s E-712 photonics alignment controller and F-131 Fast Fiber Alignment system, a hybrid approach, where a coarse position is approached with a compact motorized positioning device integrated with a high-speed piezo mechanism. The video below demonstrates the capabilities. In this demo, an in-wafer, grating-coupled waveguide device is simulated by a short length of single-mode fiber. Its input and output are coupled via lensed fibers mounted on grippers on PI’s Nanocube XYZ high-speed piezo scanner, which is controlled by the E-712 controller.
As the video demonstrates, the system is capable of extremely fast characterization and alignment speeds, and alignments in multiple degrees of freedom on the inputs and outputs are achieved in parallel. In fact, system throughput is virtually independent of the number of inputs and outputs. The system provides 25mm of XYZ motorized travel and 100 microns of XYZ high-speed travel with nanometer resolution, all closed-loop and limitable for device safety.
