ABSTRACT:
A fluid ejector head, including a fluid ejector disposed on an ejector support, and a photodetector electrically coupled to the fluid ejector. The fluid ejector head also includes a photon source photonically coupled only to the photodetector. Photons emitted from the photon source interact with the photodetector and generate an activation signal. The activation signal in turn activates the fluid ejector ejecting a fluid away from the fluid ejector.
