The first OptoElectronics and Communications Conference (OECC) was held in Chiba, Japan, 1996, as an annual conference for the researchers and engineers working in the fields of optoelectronics, optical fiber transmission, and photonic network systems in the Asia Pacific region to report, discuss, exchange, and generate ideas which advance the disciplines of optoelectronics and optical communications.

Throughout the years, OECC has become the foremost international conferences held annually in the Asia-Pacific region, entered on the optoelectronics and optical communications profession.

OECC 2021 will be held in an all virtual fomat.   OECC 2021 will continue the footsteps of its predecessors, to serve as a great platform for researchers to discuss and explore advanced technologies of optoelectronics and communications from device to system levels.
