The foreseen microlasers are based on polaritonic waveguides (GaN), an "all-in-one" active medium that is very different from usual semiconducting active layers, thus revisiting in depth the laser mechanisms.
They provide a very strong gain, low absorption losses and a self-focusing non-linearity.
The challenge is to control the laser dynamics by patterning photonic crystal waveveguides in order to realise continuous-wave or pulsed laser sources (with an ultra-low energy per pulse), and then a topological laser including an intra-cavity optical isolator.
