Fabrication-induced imperfections in photonic wire waveguides, such asroughness, stitching errors, and discontinuities, degrade theirperformance and thereby lower the yield of large-scale systems. Thisdegradation is primarily due to the high insertion losses induced byimperfections, which scale nonlinearly with the index contrast in wirewaveguides. Here we investigate the influence of discontinuities inphotonic waveguides and later show a platform that is robust tofabrication imperfections.

Sometimes, a function is called with bad inputs or in a bad program state, so it fails. In languages like Python, this usually results in an exception. But sometimes exceptions are caused by different issues or are transitory. Imagine code that must keep working in the face of caching data being cleaned up. In theory, the code and the cleaner could carefully agree on the clean-up methodology to prevent the code from trying to access a non-existing file or directory.
