Abstract
A waveguide heater is configured to heat an optical waveguide. The heater includes multiple heating elements and has one or two conditions selected from a group consisting of a first condition and the second condition. The first condition is the heater including multiple interior connectors that are each included in an interior electrical pathway between a pair of the heating elements where the interior connectors are connected in parallel and provide electrical communication between the heating elements included in the pair. The second condition is multiple exterior connectors that are each included in an exterior electrical pathway between electronics and a first one of the heating elements where the exterior connectors are connected in parallel and provide electrical communication between the electronics and the first heating element. The electronics are configured to apply an electrical bias to the heater. In some instances, the heater in included in a wavelength tuner.
