China International Optoelectronic Expo, known as CIOE, is made up of eight concurrent exhibitions: information and communication, precision optics and camera technology, lasers and intelligent manufacturing, infrared applications, intelligent sensing, photonics innovation, new display technology, and AR and VR. Together they take in the materials, components, devices, modules, equipment and solutions that go into photonic products.

Engineers, researchers and procurement teams in communications, advanced manufacturing, healthcare, consumer electronics, security, automotive and energy use it to compare components and equipment and to negotiate supply, while component makers, equipment builders and research groups reach the buyers and integrators who put photonic technology to work.
