Using Scattering to Identify Bacterial Pathogens

J.P. Robinson, B.P. Rajwa, E. Bae, V. Patsekin, A.M. Roumani, A.K. Bhunia, J.E. Dietz, V.J. Davisson, M.M. Dundar, J. Thomas and E.D. Hirleman

New advances in elastic light scattering technology allow for faster and more accurate identification of bacteria. By using globally networked libraries of unique scattering patterns produced by bacterial colonies, researchers have developed an efficient method of identifying pathogens that has potential applications in food and water safety, health care and biodefense.

Tilted Fiber Bragg Gratings as Multi-Sensors

The tilted fiber Bragg grating is a new kind of sensor that possesses all the advantages of well-established Bragg grating technology in addition to being able to excite cladding modes resonantly. This device opens up a multitude of opportunities for single-point sensing in hard-to-reach spaces.

Recollections of the First Continuous Visible Laser

Alan White worked as a member of the technical staff at Bell Labs during its heyday for industrial research. Here, he recalls his work with Dane Rigden to develop the first continuous visible helium-neon laser in 1962—and how the project evolved from covert weekend tinkering to the talk of the lab.

Light in Flight: Optical Applications in Civilian Aviation

Optical technologies such as head-up displays, fiber sensors and quantum dots will help build 21st century airplanes, connect pilots to crucial information and ensure the structural health of aircraft.
