The global photonics market will grow from $509.7 billion in 2013 to $765 billion by the end of 2020, at a combined annual growth rate of 5.8 percent, predict analysts at Transparency Market Research in Albany, N.Y. The report "Photonics Market - Global Industry Analysis, Size, Share, Growth, Trends, and Forecast, 2014-2020" says growing demand for efficient electronic products is driving the photonics market. The only restraint on the global photonics market is poor commercialization of photonic devices, analysts say.
