The history of optical test and measurement equipment, as told by contributing editor Jeff Hecht in his feature this month (see page 25), reveals a category of products that is becoming easier to use, smaller, and faster. Jeff is helping us celebrate the 50th anniversary of Laser Focus World each month by reflecting on the advances in various photonics products and technologies as we have covered them over the years. And many observations made by Jeff about past advances can be applied to the technologies described in this issue, from a new generation of quantum dots able to produce single photons (see page 45) to the nanosecond pulsed fiber lasers that can now make micro-cuts in metallic materials (see page 49).
Shrinking the size of devices while making them easier to use can be a prelude to widespread commercial adoption—a process that is beginning to happen with light detection and ranging (lidar) systems for automated vehicles from the likes of Google, Uber, BMW, and Ford. Miniature and even credit-card-size lidar systems are being introduced that could soon have a major impact on transportation and potentially many other markets, as reported in this issue by our senior editor Gail Overton (see page 39).
The prospect for such lidar systems is also the subject of a panel of investors, analysts, and product experts at the 28th annual Lasers & Photonics Marketplace Seminar, to be held February 15th during SPIE Photonics West. Other topics at the Seminar include the potentially disruptive technologies of kagome fiber, quantum cascade lasers in biomedicine, and laser projection displays and remote lighting. We will also have speakers on the state of laser markets in China, the new U.S. integrated photonics manufacturing institute, and the revival of investment in solar energy, which has implications for laser manufacturers.
At the Seminar and in our January issue, we will as always have our complete forecast for the 2016 global laser markets. Predictably, the future will hinge on easier-to-use, smaller, and faster photonics.
