New Optical Fiber Puts a Twist on Data Transmission
New research by optical fiber experts at Boston University and optical communications systems experts at the University of Southern California created a new kind of optical fiber stable enough to transmit donut-shaped laser beams called optical vortices, also known as orbital angular momentum (OAM) beams. “For several decades since optical fibers were deployed, the conventional assumption has been that OAM-carrying beams are inherently unstable in fibers,” said BU engineering professor Siddharth Ramachandran, who designed the new fiber. “Our discovery of design classes in which they are stable has profound implications for a variety of scientific and technological fields that have exploited the unique properties of OAM-carrying light, including the use of such beams for enhancing data capacity in fibers.”

New Photodetector Makes Do with Few Photons
Using a scheme based on quantum mechanics called unambiguous state discrimination, the lowest error rate yet was achieved for a photodetector deciphering a four-fold phase encoding of information. The photodetection system was demonstrated at the Joint Quantum Institute in Maryland.

Clearly Superior Epoxies for Optical Applications
Master Bond Inc.
As technology in the optics industry continues to advance and improve, careful consideration of the properties of epoxies must be evaluated. When determining the most effective adhesive to be used in opto-electronics, medical and other optic related industry applications, trade-offs of key characteristics should be assessed. Here is a guide to the different properties to consider, their benefits and potential disadvantages and advice on how to prioritize these factors for the success of the application.

SPIE Optics + Photonics is the largest interdisciplinary technical conference in North America, presenting the latest research and technologies in solar, nano, optics, photonics and space optics. The conference’s four symposia (Nanoscience + Engineering, Solar Energy + Technology, Organic Photonics + Electronics, and Optical Engineering + Applications) will offer more than 3200 presentations, including plenary and featured talks on topics such as metamaterials for molded optical wavefronts, asteroid-tracking and collision-mitigation, Kepler’s search for Earthlike planets and nanoparticle technology to convert solar energy directly into saturated steam for sterilizing tools and waste. The show also will include more than 40 professional development courses, poster sessions, panel discussions and a tribute to H. John Caulfield.

FEATURED VIDEO
AdTech Optics - DFB Quantum Cascade Laser
The DFB QCL 783 is a single-mode, high-power quantum cascade laser at 7.83 µm for high-sensitivity detection of critical greenhouse gases. The laser is capable of 280-mW continuous output power at room temperature in a single mode and with an excellent beam quality, at a wavelength previously unattainable with a semiconductor device. It allows parts-per-billion-level detection of methane and nitrous oxide for applications such as pollution monitoring and emissions control, among others.
