Researchers at the Technical University of Denmark (DTU) have shown that a Fano laser has fundamental advantages over other types of microscopic lasers. The researchers demonstrated that the coherence of a Fano laser can be significantly improved, compared to existing microscopic lasers, in work that supports future applications in integrated photonics, interfacing of electronics and photonics, and optical sensing. Fano interference could allow the realization of ultrafast and low-noise nanolasers (Fano lasers), optical transistors, and quantum devices working at the level of a single...Read full articleRelated content from Photonics MediaARTICLESSculpted Light Controls Chemical CatalystsMaterial scientists at Stanford University have developed a method to exert control over catalysts using light and advanced fabrication and characterization techniques.

In particular, it’s necessary to determine how variations in process parameters affect end results, so that acceptable process input and operating ranges can be determined.Materials processing with lasers is actually a broad term for a diverse range of applications. The major categories of these uses, and the lasers that service them, are summarized Table 1. At one...Photonics HandbookThe VCSEL Advantage: Increased Power, Efficiency Bring New Applications: Vertical-cavity surface-emitting lasers (VCSELs) differ from edge-emitting lasers in that their output beam is perpendicular to the top surface of the device instead of parallel to it.Unlike an edge emitter, a VCSEL has a maximum operating power that is not limited by catastrophic optical damage of the exit aperture because its aperture is larger and its PN junction does not...Photonics HandbookSemiconductor Lasers: An Overview of Commercial Devices: Within only a few decades, the semiconductor laser diode has evolved into a family of robust, reliable devices, with individual conversion efficiencies of better than 60 percent, continuous output powers of several kilowatts, modulation rates of several tens of gigahertz, and wavelengths from 0.4 to beyond 2 µm. This article discusses the structures and characteristics of the most common commercial varieties.Laser diodes vary widely in their wavelengths, powers, spectra and beam quality. Yet they share two fundamental components with all other lasers: an optical amplifier and a resonator that confines...Photonics HandbookLaser Safety: Important Considerations: Laser safety is nothing to scoff at; lasers can be hazardous. Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear.
