Integrated Photonics Looks to Advance Safety for Lidar
Analogous to radar, lidar uses light instead of radio frequency (RF) for detection and ranging. The first lidar systems were realized in the early 1960s, shortly after the emergence of lasers, and could send out a focused light beam and calculate distance by measuring the roundtrip time of the light signal. Since then, lidar has emerged in applications ranging from ground surveying to self-guided autonomous systems.

Measuring Up with High-Power Fiber Lasers
Fiber lasers are used in ever-increasing numbers across a range of applications. In the 2- to 20-kW-power output range, laser applications are growing in materials processing and in finesse applications such as 3D micromilling, microcutting, blind-hole machining, and additive manufacturing. According to Hexa Research, “High-power cutting and welding is a leading application in the [fiber laser] market. This could be attributed to increasing use of the product in tube cutting, flat sheet cutting, 3D cutting, car body scanner welding, power train welding, and tube welding.

An Avalanche of APD Innovations
When autonomous vehicles hit the streets, they navigate with the help of avalanche photodiodes, or APDs. These semiconductor photodetectors capture returning laser pulses as part of lidar systems, and this APD-derived data determines the distance to other vehicles, to objects, and to people — information critical for safe driving. Lidar is a fast-growing APD application, and, according to Anand Pandy, applications engineering leader at Excelitas Technologies Corp. of Waltham, Mass., cost considerations and the performance demands of lidar will lead to changes in avalanche photodiodes. “We see the trend moving from single-element APDs to arrays,” he said.

Off-axis Wavefront Measurement
TRIOPTICS GmbH
To ensure the implementation of the complex optical designs, a qualified measuring technology must be used. Wavefront measurement is particularly well-suited for this purpose, since it determines the image quality on a spatially-resolved basis, i.e. over all field angles, and across the entire sample aperture.

Quantum Teleportation-Based State Transfer of Photon Polarization in Diamond
Researchers from the Yokohama National University have demonstrated reliable quantum state transfer of photon polarization into a carbon nuclear spin coupled to a nitrogen-vacancy (NV) center in diamond. The transfer of quantum information into an otherwise inaccessible space — in this case, carbon atoms in diamond — could be applied to the transfer of sensitive information into a quantum memory without revealing or damaging the stored quantum information.

Researchers from the Moscow Institute of Physics and Technology (MIPT) Center for Photonics and 2D Materials have synthesized a quasi-2D gold film, showing how materials not usually classified as two-dimensional can form atomically thin layers. The researchers said 2D metals bring them closer to a new class of optical metamaterials whose potential to control light could lead to unexpected technologies.
