Automated PIC and Wafer-Level Test Framework Proliferation
#1Software-defined automated test benches for photonic integrated circuits are transitioning from research demonstrations to production deployment at major photonics manufacturers. Systems integrating swept laser sources, automated probe stations, and control software (e.g., Keysight's PIC test solutions, FormFactor's photonic wafer probing systems, and custom Python/LabVIEW pipelines at merchant PIC foundries like IMEC and AIM Photonics) can execute full device characterization — insertion loss, crosstalk, spectral response, modulation bandwidth — without technician involvement beyond initial setup. Automated Mach-Zehnder interferometer tuning to 7–8 bit resolution and wafer-level SNSPD testing have been demonstrated in academic settings and are moving toward production adoption.
