Dr. Linden is a Senior Scientist at Vox Biomedical LLC, responsible for initiating and managing photonics-related R&D activities leading to advanced components and instruments. Projects fall into the areas of photonic semiconductor materials, lasers, LEDs, detectors, solar cells, components, subassemblies, fiber lasers, and photonic device-based equipment for biomedical applications, genetic/proteomic based analytical instruments, homeland security, and military applications. Current activities involve visible, infrared, and terahertz semiconductor lasers, mid-IR fiber lasers, solar cells and associated instruments. Dr. Linden taught optoelectronics and microelectronics courses for over 30 years, both at Northeastern University and in the MIT Summer Program, as well as at numerous in-house corporate training sites. He currently teaches photonics courses for SPIE. He produced several nationally-televised tutorial video recordings for NTU, and has written a CD-ROM book on Diode Lasers and Optical Detectors. He is also a regular tutorial instructor on diode lasers and detectors at annual SPIE conferences, and has presented numerous lectures at local and regional meetings, as well as workshops on diode lasers at the annual meeting of the American Society of Lasers in Medicine and Surgery. He has presented tutorial material on photonics in training patent examiners at the U.S. Patent and Trademark Office (USPTO). Dr. Linden chaired annual SPIE conferences on Photodetectors, as well as Terahertz and Gigahertz Electronics and Photonics, is a reviewer for the technical journals Applied Physics Letters, Journal of Applied Physics, and Photonics Technology Letters, and has served as an expert witness on optoelectronic-device related cases. Dr. Linden is a senior life member of the IEEE, a member of the Optical Society of America (OSA) and SPIE, a supporter of the Technion, and was previously inducted into honor societies Tau Beta Pi, Eta Kappa Nu and Sigma Xi.
