Automated, deep reactive ion etching free fiber coupling to nanophotonic devices

Rapid development in integrated optoelectronic devices and quantum photonic architectures creates a need for optical fiber to chip coupling with low losses. Here we present a fast and generic approach that allows temperature stable self-aligning connections of nanophotonic devices to optical fibers. We show that the attainable precision of our approach is equal to that of DRIE-process based couplings. Specifically, the initial alignment precision is \(1.2\pm 0.4\mu m\), the average shift caused by mating \(
