Nonrepeating photonic crystal may enable more tunable, reliable semiconductor lasers

Over the past two decades, photonic-crystal surface-emitting lasers (PCSELs) have shown promise as a type of advanced semiconductor laser useful in defense- and aerospace-related applications. Typically, these devices are made with photonic crystal patterns that repeat across the area of the…
