Why study Optical Technologies or „Photonics“ as this field is sometimes called. Let’s start with a video by the European Research Council, the public body for funding of scientific and technological research conducted within the European Union.
Photonics – the science of generating, controlling and detecting light – is the future
The field of optical technologies focuses on the generation, control, measurement, and – above all – use of light in virtually every area that is vital to society and the economy. The term „photonics“ refers to the photon, the light particle, just as „electronics“ refers to the electron.
Light has extraordinary properties which include:
- focusability down to one millionth of a millimetre (nanometre)
- the highest achievable speed in the universe
- shortest pulses of one billionth of a billionth of a second (attosecond)
- highest output of up to billions of megawatts (petawatt)
- undisturbed interaction: up to millions of megabits per second (terabits per second)
Applications
Photonics puts these properties to use. The selection of examples shows that light and optical technologies are everywhere. Photonics is key to any technological development in the modern world. MAOT graduates can become part of all these amazing technologies – both as experts in highly specialised small companies or as specialists in major global players.
Lasers are everywhere. The list of laser applications for industry and science is almost endless: from spectroscopy techniques to digital cinema projectors, from laser welding technques to laser scalpels, and many more…
Microchips are used in almost every electronic device we use today. Microchips are produced by Photolithography – with light.
Optical fibres are the backbone of the worldwide internet – the basic structure of modern life.
Light is essential for the automotive industry. It’s „more than just headlamps“ but is used in the production line, development of new materials, driver assistance systems and more.
Solar cells: Light provides energy. Solar cells are an essential component of the energy transition to fight climate change.
We have to admit, that some dreams – although very desirable – will never come true. Watch here :-).
Nobel prizes
The importance of optical technology to science is reflected by several Nobel prizes connected to optical technologies awarded in recent years. Inthis video Nobel laureate (2018) Donna Strickland explains why „Photonics is going to be the technology of the 21st century“.
