    Abstract: Disclosed herein are electronic devices that include arrays of dual function light transmit and receive pixels. The pixels of such arrays include a photodetector (PD) structure and a vertical-cavity, surface-emitting laser (VCSEL) diode, both formed in a common stack of epitaxial semiconductor layers. The pixels of the array may be configured by a controller or processor to function either as a light emitter by biasing the VCSEL diode, or as a light detector or receiver by a different bias applied to the PD structure, and this functionality may be altered in time. The array of dual function pixels may be positioned interior to an optical display of an electronic device, in some cases to provide depth sensing or autofocus. The array of pixels may be registered with a camera of an electronic device, such as to provide depth sensing or autofocus.
