DTU nanolaser is constructed in a semiconductor membrane that causes electrons and light to gather within a confined space (blue shadow).
An energy-efficient nanolaser based on “extreme dielectric confinement” within a nanocavity takes us a step closer to on-chip data being transmitted entirely via photons.

FIGURE 1. Operating principle of a thermoelectric cooler based on the Peltier effect: When current flows through the semiconductor elements between ceramic substrates, heat is absorbed at the cold side and rejected at the hot side to create a controlled temperature differential across the device.
