Abstract
Planar nanophotonic circuits allow for realizing complex optional functionality by joining photonic library elements with waveguides into integrated optical circuits. The restriction to quasi-two-dimensional geometries imposes constraints for advanced photonic devices. Here I will present recent results on hybrid 2D-3D photonic integration to overcome these restrictions. I will introduce broadband coupling geometries which enable low-loss out-of-plane optical coupling. I will further present a reconfigurable photonic device architecture which allows for implementing desired optical filter functionality after planar fabrication. This way flexible and reconfigurable integrated optical circuits come within reach which provide desired output in analogy to programmable integrated electrical circuits.
