The Aharonov-Bohm Effect, an exotic physical phenomenon, has been directly observed for the first time, following decades of attempts.

The finding could lead to topological phases, and eventually to ...

Unlike traditional spectrometers, however, this one is designed using freeform optics, a relatively recent advance that upends more than a century of optical design.

For more than 125 years, optical design was constrained to using rotationally symmetrical, often perfectly spherical surfaces placed in round tubes—for example, single-lens reflex cameras and microscope objective lenses.

Another paper published in June in , an Optical Society Journal, focused on the fabrication and testing of the convex grating.

Two future papers, coauthored by researchers from both Rochester and UNC–Charlotte, will describe the fabrication of the mirrors as well as the fabrication and assembly of the full prototype.This research may have applications in improving the ...In a key step toward making large-scale optical neural networks practical, researchers have demonstrated a first-of-its-kind multilayer all-optical artificial neural network. Researchers have developed a way to enhance the imaging speed of two-photon microscopy up to 5 times without compromising resolution.What we found here can be applied to spectrometers used in all of these other applications,” says Rolland.“That is the power of freeform optics.” The project is funded by the University’s Center for Freeform Optics (Ce FO), a collaborative initiative funded by the National Science Foundation and directed by Rolland, which also involves the University of North Carolina at Charlotte and multiple industry partners whose membership dues fund the research.For the first time, a team has sent a light particle entangled with matter over 50 km of optical fiber.This paves the way for the practical use of quantum networks and sets a milestone for a future ...Engineers have made major improvements on their design of an optical neural network -- a device inspired by how the human brain works -- that can identify objects or process information at the speed ...Scientists have developed an algorithm that can determine whether a super-resolution microscope is operating at maximum resolution based on a single image. Researchers have modeled a method to manipulate nanoparticles as an alternative mode of propulsion for tiny spacecraft that require very small levels of thrust. With freeform optics, computer numerical control and new diamond turning technologies, it is now possible to dispense with conventional, rotationally symmetric mirrors and lenses, and design more complicated optical surfaces that can correct the aberrations that limit field of view and resolution, resulting in optical devices that require fewer, smaller lenses and mirrors that are more effective than traditional ones., University of Rochester researchers Jannick Rolland and Jacob Reimers describe an optical device with potential applications ranging from improved satellite and diagnostic imagery to more precisely matching the paint color on a living room wall.The device is a type of spectrometer—an optical instrument that takes light and breaks it down into components to reveal a catalogue of information about an object.
