Lasing from a Self-Assembled Photonic Crystal
Researchers in India have developed a mirrorless photonic crystal laser made out of dye-activated, self-assembled nanoscale spheres.
A source excites dye molecules in a nanophotonic structure generating the spontaneously emitted light within the structure. At higher excitation energy, the stimulated emission overcomes the spontaneous emission, which leads to lasing.
Researchers in India have developed a mirrorless photonic crystal laser made out of dye-activated, self-assembled nanoscale spheres. The tiny laser emits visible wavelengths at room temperature and takes only a few hours to build (Phys. Rev. A 85, 023844).
