Single-crystalline Mg 3 N 2 thin films are grown on MgO (100) substrates with plasma-assisted molecular beam epitaxy. To prevent the oxidation of the Mg 3 N 2 films and allow further physical characterization, a polycrystalline MgO cap is deposited in situ. The growth orientation of the Mg 3 N 2 films can be tuned from (100) to (111) by...

We experimentally demonstrate the difference between a ridge polariton laser and a conventional edge-emitting ridge laser operating under electron-hole population inversion. The horizontal laser cavities are 20-60µm long GaN etched ridge structures with vertical Bragg refectors. We investigatethe laser threshold under optical pumping and assess...

To highlight the specific character of polariton lasers, namely the absence of reciprocity between the processes leading to gain and loss, we present here the operation of a CW polariton laser in a ridge geometry with distributed Bragg reflectors (DBRs) forming the cavities. We explore the laser threshold under optical pumping, and we...
