We're working on photonic crystal lasers, which are interesting because they're extremely fast, have low threshold (require little power to turn on), and are extremely compact.  In addition, many different frequency channels can be packed onto the same chip and combined onto a common fiber, which makes them particularly interesting for telecommunications and signal interconnects.   In this project section, we discuss our research on photonic crystal lasers in the context of the general PC laser field, and in the broader context of lasers and modulators for telecommunications and possible future interconnects.  We also describe our lasers in greater detail than was possible in the papers (below), and give additional data.
