Abstract
Embodiments herein describe using an actuator to tune a waveguide. In one embodiment, the tunable waveguide includes a gap between the waveguide and cladding. The actuator can compress the cladding to shrink this air, bringing the cladding closer to the waveguide. Doing so changes the effective refractive index of the waveguide. Alternatively or additionally, the actuator can increase the gap.
