Five photonics trends for 2018
The year is ending, holiday reminders surround us, and after some opulent dinner it is time to think about what may come to us next year. A few trends in photonics such as lidar or additive manufacturing are obvious, others may be less apparent. Here are my picks for photonics trends that might be worth watching in 2018.
2017 was an incredible year for industrial photonics: Market leaders such as Trumpf and IPG Photonics posted double-digit revenue growth, and Coherent seems to do well with the purchase of Rofin Sinar. It is no surprise that fiber lasers conquered more than 40% market share, while the good news for excimer lasers may not be on everybody‘s focus. And thanks to EUV the good old CO2 laser has some new prospects as well.
Behind many of the good numbers is a record breaking spending of almost $56 billion for equipment in semiconductor industry. The CEO of Carl Zeiss, Michael Kaschke, spoke of “the most successful fiscal year in the history of Zeiss,” backed by a 25% increase of the SMT division, which mainly delivers into the semiconductor industry.
Think big: Lidar
There is no need to consult with glass balls or the dubious remains in my coffee mug to predict the future of lidar. While this technology has been around for decades to analyze the distribution of gases and pollutants in the atmosphere, it has become a crucial technology for autonomous driving in recent years. A short Google research reveals a list of more than 50 companies active in this market.
VCSELs on the rise
Another interesting trend is VCSELs. These vertical-cavity surface-emitting lasers received some attention recently when Apple announced it is investing $390 million in VCSEL-maker Finisar. While VCSELs have been used in the iPhone 8 (mainly from Lumentum), Apple announced more to come: “In the fourth quarter of 2017, Apple will purchase 10 times more VCSEL wafers than were previously manufactured worldwide over a similar time period.” The technology gives a cheap and integrated solution for depth sensing and, hence, for 3D image acquisition. We see it in smartphones now, but this might be just the beginning.
Additive manufacturing
The best place to see the progress in additive manufacturing was certainly the Frankfurt tradeshow formnext, held in November. With more than 21,000 visitors and 470 exhibitors in its third year, it reached an audience similar to established trade shows such as SPIE Photonics West.
But this reflects just the general trend of 25% CAGR for (laser-based) additive manufacturing over the last five years, as Arnold Mayer from Optech Consulting confirmed to me last week. The Boston Consulting Group forecasts even 30% annual growth in a larger market review on Industrialized Additive Manufacturing.
Basic research: Make America great again?
The headlines for quantum technologies were big in 2017: Using their Micius (or Mozi) satellite, the Chinese achieved quantum encrypted communication over a distance of a 1200 km. They established a network of five ground stations to communicate with Micius. These connect to a 2000-kilometer fiber optic backbone between Beijing and Shanghai (completed in 2016). They made the first satellite-based quantum key distribution to start an encrypted video conversation with the wise man of quantum communication, Anton Zeilinger, in Vienna, Austria.
What does that mean for my forecast? In 2018, the call for funding applications within the European €1 billion Quantum Technology Flagship will start. This comes along with approximately two dozen national initiatives. In China there will be ongoing strong governmental funding plus private money: In October 2017, the Alibaba group announced their plans to invest more than $15 billion over three years in researching emerging technologies including artificial intelligence and quantum computing.
And after all, this new infrastructure as well as similar projects in Asia will draw the attention of young talent. Already, the ELI project employs almost 1000 people on various places. It will be very interesting to follow up on the American reactions in 2018.
So 2018 will be a very interesting year. While most of the industry is flourishing, it looks as if some decisions in basic research may change (or retain) the picture of our community for decades.
