Efficient light amplification in low gain materials due to a photonic band edge effect
One of the possibilities of increasing optical gain of a light emitting source that the emission wavelength of the light source with gain falls close to the photonic band edge of the PhC, then due to low group velo...

Enhanced photoluminescence extraction efficiency from a diamond photonic crystal via leaky modes
Two-dimensional photonic crystal can be exploited as the top part of a light source in order to increase its extraction efficiency. Here, we report on the room-temperature intrinsic photoluminescence (PL) behavior of a nanocrystalli...

Light emission dynamics of silicon vacancy centers in a polycrystalline diamond thin film
Diamond thin films can be, at a relatively low-cost, prepared with a high-density of light-emitting negatively charged silicon vacancy (SiV) centers, which are composed of diamond grains with both the SiV centers and sp2-ca...
