Glass-based 1-D dielectric microcavities

We have developed a reliable RF sputtering techniques allowing to fabricate glass-based one dimensional microcavities, with high quality factor. This property is strongly related to the modification of the density of states due to the confinement of the gain medium in a photonic band gap structure. In this short review we present some of the more recent results obtained by our team exploiting these 1D microcavities. In particular we present: (1) Er3+ luminescence enhancement of the 4I13/2 → 4I15/2 transition ; (2) broad band filters based on disordered 1-D photonic structures ; (3) threshold defect-mode lasing action in a hybrid structure.
