Photonics – the technology of light

Tom Ako
Photonics is concerned with the control of photons. As a technology, photonics focuses on manipulating light to achieve some practical goals like telecommunication, sensing, industrial processing etc. In photonics, photons are controlled in many ways e.g. switching, re-routing, modulation and amplification. As semiconductors have become more important in optics, we have seen the emergence of hybrid fields where electronics and light come together. For example, we have electro-optics: devices...
