Open Micro Cavities

We develop open micro cavities to trap light in small volumes and thereby increase the interaction with intra-cavity emitters. Important aspects in this development are the optical penetration in the mirrors, coupling between optical modes, and scattering and clipping losses.

Illustration of planar and plano-concave cavity modes. The green areas indicate standing waves in the cavity. The blue and red areas indicate the high and low index materials of the DBR mirror.
