Single-mode quasi-L2 photonic crystal micro-cavity for 1.3 µm InAs quantum dots light sources

We design and realize a single mode qL2 photonic crystal defect cavity near the 1.3 mum band. Taking advantage of its small mode volume, 1.3 mum InAs quantum dot light emitters with this cavity exhibit an emission intensity as high as 70 times over the ones without it.
