Abstract
Optical integrated circuits are disclosed having a gap traversing the lens or the waveguide grating and an actuator that controllably positions the optical integrated circuit on each side of the gap. As a result, the thermal sensitivity of the optical integrated circuits, for example, arrayed waveguide gratings, is mitigated. Also disclosed are methods for fabricating optical integrated circuits employing the gap and actuator.
