The status of present optic technology in turbine engine control is highlighted, and future developments and trends are explored. Attention is given to a base engine control system configured with a primary and backup or standby control. Specific needs for integrated optic components in advanced turbine engine control systems are addressed. The optic harness and interconnect, as well as the electrooptic interface involving only coupling optic excitation and return signals are discussed. A number of 1:2 and 1:5 power splitters and combiners being fabricated using the ion-exchange technology on glass substrates are shown. The devices are potentially useful for the combination of various optical signals from a number of sensor units, and in addition calibration signals could be added prior to signal processing. Integrated optic and electrooptic interfaces are expected to evolve into the engine control environment. A concept for a multilayer electrooptic module which contains a single or multiple optic layers within the printed wiring card is illustrated.
