"lasers have physical limits on how small they can be while remaining functional, overcome using light-trapping nanocavity allowing room temperature laser operation at exceptionally low power... ultra-compact so 1000's lasers integrated onto single microchip... halves computer/ data center energy consumption, faster with minimal heat/ energy loss... high-resolution imaging, ultrasensitive biosensors, seamless transition from fiber optics into chip's internal architecture... future: electrical pumping"
