RESEARCH & DEVELOPMENTWith decades of accumulated expertise in the development of photonic technologies to rely upon, Hamamatsu Photonics conducts basic research to discover new knowledge and create new industries in the elds of biotechnology, medicine, information technology, communications, energy, materials, astronomy, and agriculture. We also strive to continuously develop exciting new products and enhance existing products with added functionality. In scal year 2017, funds allocated to research and development totaled JPY 11,776 million, a decrease of 0.8% over the previous scal year. Some highlights of our R&D efforts are presented here. Basic researchPromoting basic research for ultrafast quantum simulatorsIn the photonics basic research sector, we are pursuing research on an ultrafast quantum simulator. In materials, atoms and molecules exchange energy. And such phenomenon determines the characteristics of products such as semiconductor devices, superconductors, and drugs. A quantum simulator is a device for performing simulations of the activity inside an articial atomic ensemble to clarify this mechanism, and is expected to assist the development of new products, including new functional materials and new drugs. Using the spatial light modulation technology the Company has cultivated over many years, it has created technology for forming arbitrary optical patterns with excellent reproducibility(*1). This is one of the photonics technologies required to develop a quantum simulator, and is used to examine the effect that stimulation from an external source exerts atomic ensembles. Moreover, we can anticipate further research and development because this technology is not limited only to pure research but can be applied to new super-resolution microscopes and three-dimensional measurement technology as well.(*1)This result was achieved through joint research with the Institute for Molecular Science of the National Institutes of Natural Sciences, based on “Addressing Quantum Many-Body Dynamics by Ultrafast Coherent Control with Attosecond Precision”, a Grant-in-Aid for Scientic Research (Specially Promoted Research) from the Japan Society for the Promotion of Science.Schematic view of ultrafast quantum simulator in which atoms are assembled into an articial strongly correlated system(Courtesy of Prof. Ohmori, Institute for Molecular Sciences, National Institute of Natural Sciences, Japan)An externally applied stimulus alters electron orbits creating electron wave packets reaching internally throughout the atomic assembly.Electron orbit in atomAtomicnucleusElectron “wave” packetExternal stimulusApprox. 0.5 microns8
