Absolutely. A 2.4 micron beam splitter is a hell of an achievement. I don't know what the next closest is in size, but the vast majority of beam splitters I'm familiar with are measured in millimeters. I'm sure there are others doing work on miniaturization, but 2.4 micron would seem like genuine landmark progress. What we need next is a practical photonic transistor at these scales!
