JENOPTIK Further Expands Manufacturing Capacity with a New Class 5 Cleanroom25 October 2017, Jupiter, FL USA — Jenoptik Optical Systems, LLC, a leading worldwide supplier of high performance optical solutions, announces the expansion of its manufacturing operations in Florida. Jenoptik opened a new ISO 14644 Class 5 cleanroom with state-of-the-art filtration technology for high-precision optical assemblies to support applications with demanding cleanliness requirements like semiconductor and space flight instrumentation. Additionally, Jenoptik has extended site capabilities by investing in a new thermal vacuum chamber in the cleanroom. The Class 5 cleanroom complements the pre-existing ISO 14644 Class 7 cleanroom and triples the amount of cleanroom space in Florida.
Jenoptik’s continued expansion in Florida is the direct result of customer volume requirements for the company’s products. This new facility complements the cleanroom capacity in Huntsville, AL. The Huntsville facility is purpose-built to meet the rigorous requirements of leading-edge semiconductor-related manufacturing activities.
Jay Kumler, President of Jenoptik Optical Systems in North America, commented, "We are investing in differentiating technologies, advanced equipment and employees, and we are committed to meeting our customers’ expectations for higher levels of cleanliness and contamination control.”
Leading equipment manufacturers around the globe rely on Jenoptik’s products to build semiconductor devices, telecommunications equipment, digital projection, mobile devices, augmented reality, industrial automation and connected vehicles. Our optical systems are helping lead the digital transformation and internet of things.
Jenoptik looks forward to the new opportunities the expansion will provide and the partnerships that will be the result of their success. For additional information on Jenoptik’s capabilities please visit www.jenoptik-inc.com

The invention and development of all-electronically tuned quantum cascade lasers has made it possible to obtain spectral information, covering over 1 µm in the long wave infrared region, regarding absorbers in less than fraction of a millisecond. The electronic tuning is achieved through the use of a acousto-optically generated phase grating in a crystal. As described previously, the acousto-optic modulator (AOM) tuned QCL is capable of switching lasing wavelengths in time of the order of 0.5 µs, regardless of the size of the wavelength step. The wavelength tuning is achieved via change in the acoustic wave RF frequency. Thus, a complete spectrum covering > 1 µm tuning (for example from ~8.5 µm to ~ 9.5 µm) can be obtained in less than 20 µs, when the RF frequency is changed in response to an analog drive. For experimental reproducibility of spectra, we have implemented a digital scanning system that permits selection of step size and step speed. Using the AOM tuned QCL, we have carried out a number of studies to explore the usefulness of rapid scanning QCL systems. One study involves spectroscopy of liquids. Since almost all liquids absorb very strongly in the long wave infrared region, we have used attenuated total reflection (ATR) to study liquids such as isopropyl alcohol (IPA), ethanol, water, various alcoholic beverage such as vodka, gin and scotch, 2,2,2-trifluroethanol and Epsom salt dissolved in water. In each case a complete spectrum from ~8.5 µm to ~ 9.5 µm is recorded in a single shot 500 µs scan. From these studies, we can verify the claimed “proof” of the alcoholic beverages. In another study, we have explored mixing of gases (R134A HFC bolus injected into a fast flowing stream of air) in a flow tube where time dependent spectra of mixing gases are obtained in >600 consecutive shots during a 300 ms time span. I will describe both studies in detail, including a video showing the flow mixing evolution on millisecond time scale. The fast spectroscopic study of liquids now opens up the potentially exciting area of real time process monitoring in chemical, biological and food and wine industry. The transient flow spectroscopy study clearly indicates that the AOM tuned QCL system will be of immediate use in supersonic flow studies and in the study of combustion and explosion dynamics.
Dr. C. Kumar N. Patel is the Founder, President and the CEO of Pranalytica, a company located in Santa Monica, CA, specializing in high power quantum cascade lasers and applications. Pranalytica is the leader in QCL technology through its invention of a radically QCL new structure design, called the non-resonant extraction, which has allowed Pranalytica to offer commercial QCLs that produce highest powers anywhere in the world. He is the inventor of the carbon dioxide, carbon monoxide, and the Spin-Flip Raman lasers. He pioneered the use of these and other lasers to measure trace gases in difficult environments. He was at AT&T (now Lucent Technologies) Bell Laboratories for thirty-two years and was Executive Director of the Physics Division and of the Materials Research Division. Under his leadership, Bell Labs produced some of the most critical technologies for optical communications. The quantum cascade laser was also invented in Physics Division during his leadership. From 1993 to 1999 he was the Vice Chancellor for Research at UCLA. Dr. Patel was elected to the National Academy of Science in 1974 and the National Academy of Engineering in 1978. Dr. Patel has received every major scientific honor in the United States. He received the National Medal of Science given by the President of the United States in 1996. In 2012, he was inducted into the National Inventors’ Hall of fame. In recognition of the CO2 laser’s importance to the medical field, he has been elected as an Honorary Member of the Gynecologic Laser Surgery Society in 1980 and in 1985 he was elected an Honorary Member of the American Society for Laser Medicine and Surgery.

Seminar: "Completing Bohr’s Complementarity" by Xiao-Feng Qian

The understanding of the nature of light has been one of the most fundamental and ancient issues of science history. Wave and particle are two dominating interpretations of light. The debate of light being either a particle or a wave has gone back and forth over the centuries from Newton’s corpuscular theory and Huygens’ wave description in the 17th century, through the prevalence of wave interpretation in the 19th century due to Fresnel, Young, and Maxwell, all the way to Einstein’s photoelectric effect of photon description and de Broglie’s matter wave theory in early 20th century. The widely accepted qualitative resolution has been Bohr’s complementarity principle which states that light is actually BOTH wave and particle but they are two mutually exclusive properties . Initiative search of a comprehensive quantitative analysis of this wave-particle duality picture wasn’t carefully pursued until around the 1980s by Wootters-Zurek, Glauber, and Mandel . The consequence has been the famous complementary constraint relation for single photons, i.e., D2 + V 2 1, repeatedly rediscovered around the 1990s by Greenberger-Yasin, Jaeger-Horne-Shimony, and Englert , with visibility V representing wave property and distinguishability D labeling particle behavior. Unfortunately, even almost 40 years after its discovery, no careful attention has been paid to the fact that the inequality D2 + V 2 1 embodies neither completeness nor exclusivity, two essential factors of Bohr’s complementarity. Something must be missing. We solve the issue by performing a quantitative analysis of light’s wave and particle (ray) properties in the classical regime. We recover the relation V 2 + D2 1 for a generic classical light field. By taking into account a previously neglected third key property of the field, i.e., classical entanglement (measured by concurrence C ), a generic complete three-way complementary relation V 2+D2+C2 = 1 is observed for the first time to satisfy both completeness and exclusivity. Experimental results of an optical beam interfering through a Mach-Zehnder interferometer has confirmed the theoretical predictions . The three-way relation reveals fundamental coherence constraints of light fields, and it also suggests a modified view of the traditional complementary wave-particle duality for light. The results are also valid for single quantum particles indicating its universality. This work is the result of collaboration with J.H. Eberly and A.N. Vamivakas at Rochester.
