A direct nanoprinting technique is used to fabricate a pit arrangement on the surface of an organic amorphous emissive layer. A pit arrangement with a closely packed hexagonal pattern with a 400 nm pitch is successfully fabricated within 60 s. Pit depth is more than 70 nm and depends on press pressure. The fabricated structure is considered to be a photonic crystal band edge laser, and laser oscillation is confirmed by optical excitation. It is also confirmed that the oscillation threshold can be controlled simply by changing the press pressure used in the direct nanoprinting procedure. The results show that the use of the direct nanoprinting technique enables the fabrication of organic nanostructure devices such as photonic crystal band edge lasers with an organic emissive material.
