Optoelectronic is a word that is used to describe devices that combine light and electronics. While this term is commonly used, there are a number of synonyms that can be used to describe these types of devices. One alternative term that could be used is photonics, which is actually a broader term that describes the science and technology of light. Another possible synonym is electro-optics, which refers specifically to the manipulation of light using electrical fields. Other related terms include lightwave electronics, photonic devices, and integrated optics. Ultimately, the choice of terminology depends on the context and the specific application being discussed.
