A new award of $4.5M is set to fund CHIRP, the CHanneled Infrared Polarimeter, a compact tool that can provide scientists with extremely accurate data essential, and previously unattainable across all conditions, for long-term climate change modeling. Principal Investigator (PI) Meredith Kupinski, associate professor of optical sciences at the Wyant College of Optical Sciences, and Science PI Sylvia Sullivan, assistant professor of chemical and environmental engineering at the College of Engineering, are leading the project as part of NASA’s Earth Science Technology Office (ESTO) Instrument Incubator Program (IIP). NASA Press Release. The Instrument Incubator Program funds novel instruments, like CHIRP, to launch new technologies for future Earth-observing missions focused on pursuing pressing Earth science phenomena.

In the 1990s, the company began to grow both on its own and through acquisitions.[5] It purchased Litton Systems' silicon carbide group from Northrop Grumman in the 1990s,[5] Virgo Optics in 1995,[8] and Lightning Optical Corporation in 1996,[8] among others. The combination of Virgo and Lightning created II-VI's VLOC division for developing one-micron solid-state lasers.[8] Acquisitions in the 2000s have included Laser Power Optics in 2000; Marlow Industries in 2004;[9] HIGHYAG (75% in 2007[10] and the remaining 25% in 2013); Photop Technologies in 2010;[11] Oclaro's Santa Rosa, California, optics coating facility in 2012; Anadigics and EpiWorks in 2016;[12] and Integrated Photonics in 2017.[13][8] The acquisition of Avalon Photonics, Anadigics, and EpiWorks allowed II-VI to increase its production of vertical-cavity surface-emitting lasers (VCSELs),[8] important to 3D sensing technology; and the acquisition of Finisar Corporation in 2019 brought to II-VI Finisar's high volume 3DS VCSELs indium phosphide (InP) platform and its experience in integrating InP lasers with optics and electronics in transceivers.[8] Acquisitions of INNOViON, Ascatron, and some of GE's patents have expanded its business in silicon carbide substrates.[8] In 2022, II-VI acquired laser manufacturer Coherent, Inc..[14] and took the name Coherent Corp.

The Saxonburg headquarters site was once the property of KDKA, the world's first commercially licensed radio station, and some of the original structures are still there.[20] In the 1940s, the site was expanded by the Carnegie Institute of Technology and the U.S. Nuclear Regulatory Commission to become a 400 MeV synchrocyclotron research facility.[21] II-VI acquired the property around 1978 and has further expanded the facility over the years.[22]

Coherent was founded as II-VI Incorporated in 1971 by Carl Johnson and James Hawkey.[5][6] The name "II-VI" is a reference to the groups II and VI in the periodic table, since the company started its business by producing cadmium telluride (cadmium belongs to group II and tellurium belongs to group VI).[7] The company's first products included lenses, windows, and mirrors for CO2 lasers.[5]

Thomas L. Koch’s term as dean of the Wyant College of Optical Sciences has been defined by 13 years of tremendous growth amidst the continuing explosion of applications and demand for new optics and photonics technologies. Provost Ron Marx said, “Dean Koch has led the Wyant College of Optical Sciences with outstanding leadership and unwavering dedication. He has been a champion of one of our unique strengths in science and engineering here at the University of Arizona. We are deeply grateful for his service.”

Carl Johnson served as II-VI's first CEO from 1985 to 2007. He stepped down as CEO in 2007 and was named chairman of the board, a position he held until 2014.[15] Johnson was succeeded as CEO by Francis Kramer, who had been president since 1985.[13] Kramer followed Johnson as chair in 2014, in addition to his duties as CEO, and continued as chair in 2016 when Vincent D. (Chuck) Mattera, Jr., became the company's third CEO.[8] In November 2021, Kramer transitioned from chair to Chair Emeritus, and Mattera was named chair and CEO.[16] In February 2024, Coherent announced that Mattera would retire, remaining in place until a successor is named.[17] Jim Anderson was named CEO in early June of 2024. He was formerly with Lattice Semiconductor Corporation (LSCC)

This colloquium will give a brief introduction to reservoir computing, an overview of its theoretical foundations, including the notion of a universal family of reservoir computers that is capable of approximating a certain family of nonlinear maps from input sequences to output sequences, as well as its inherent limitations. It will then motivate and touch on efforts by the speaker and his collaborators to exploit noisy near-term quantum computers as quantum reservoir computers. Finally, the colloquium will conclude with a discussion of research directions for further development of quantum reservoir computers as well as research trends in the broader recent efforts on engineered physical learning machines going beyond reservoir computers.
