Quantum Dots Enhance Stability of Perovskites for Solar Power
A team from the University of Toronto is researching materials that could enhance the solar-harvesting potential of silicon by absorbing wavelengths of light that silicon does not absorb. The researchers have demonstrated that perovskite crystals and quantum dots, working together, could increase the stability of solar materials.

Quantum Interferometry Reveals How Coherent Phonons Are Generated
Scientists at Tokyo Institute of Technology and Keio University wanted to investigate ways to store, move, and process information at exponential speeds using heat and noise (also known as waste vibrations). To do so, they studied the excitation and detection of photogenerated coherent phonons in gallium arsenide (GaAs) semiconductors using an ultrafast dual pump-probe laser.

Canon Surface Reflectance Analyzer
Canon U.S.A. Inc., Industrial Products Div.
Canon RA-532H, Surface Reflectance Analyzer (goniophotometer), is a compact, portable device capable of measuring 4 surface appearance conditions in a single pass: gloss, haze, image clarity (IC), and BRDF (Bidirectional Reflectance Distribution Function). Additionally, Canon has recently released its own new parameter, “Scattering” parameter, overcoming the shortage of both IC and DOI (Distinctiveness of Image) when evaluating matte and textured surfaces as well as orange peel surface.

VCSELs and Their Role in the Evolution of Photonic Systems
Wed, Jun 5, 2019 1:00 PM - 2:00 PM EDT
In this webinar, professor Axel Scherer, who with Jack Jewell created the first prototypes for VCSELs while Scherer was at Bellcore in the 1980s, will discuss his role in the development of these miniature lasers and how their use has evolved as the technology has progressed. Scherer will discuss VCSEL design, lasing characteristics, and the capabilities that make VCSELs well suited for use in today's photonic and optics applications, compared with other technologies such as LEDs.

Stabilizing the Line of Sight: LOS Dynamics and Control
Thu, Jun 6, 2019 1:00 PM - 2:00 PM EDT
This webinar, presented by the author of Stabilizing the Line of Sight (Photonics Media Press, 2018), will provide an overview of the issues and topics that must be addressed to successfully implement Line of Sight (LOS) control and stabilization design. Presenter Peter Kennedy will cover LOS pointing, tracking, and stabilization, with a focus on LOS definition, performance, architecture, and basic theory. He will provide a general methodology for LOS stabilization system design and identify critical algorithms for analyzing stabilization techniques. The objective of the webinar is to provide attendees with a firm grounding in LOS stabilization, so that they will be able to address the detailed design tasks required to perform an actual design.
