Managing Holography Errors in Asphere Metrology
Aspheric lenses are preferred over conventional spherical lenses in many optical systems for their high optical performance and lightweight and compact form factor. However, measuring aspheric surfaces is not a straightforward process. Metrology options are typically based on interferometry or profilometry. To measure an asphere interferometrically, the reference wavefront must match that of the nominal aspheric form. A computer-generated hologram aspheric null achieves this by converting the wavefront from the aspheric surface into a spherical wavefront and superimposing it over the reference wave in the interferometer.

Exploring the Role of High-Purity Laser Light in Quantum Technology
A second quantum revolution is underway. The first revolution relied on an understanding of the wave-particle duality of electrons and photons, and led to the information age of smartphones, the internet, and supercomputers. Inventions of the second quantum revolution, known as Quantum 2.0, go beyond wave-particle duality to exploit the quantum-mechanical effects of superposition and entanglement. Examples include early prototype quantum computers for performing previously intractable calculations, quantum sensors that measure physical quantities with unprecedented sensitivity, and a new generation of ultraprecise atomic clocks.

Capturing Solar Images in the Extreme Environment of Space
Imagine trying to take pictures or make optical measurements on a cloudless day beneath the blistering onslaught of 13 suns. This is the equivalent reality for the European Space Agency’s (ESA’s) Solar Orbiter and NASA’s Parker Solar Probe (PSP), the latter of which is currently operating in temperatures of almost 1640 K in the inhospitable environment around the sun.

Researchers at ITMO have shown that individual atoms can be transformed into polaritons — quantum particles that are a mixture between matter and light, which are transmitted via optical fibers. The research may have applications in quantum computing in the form of quantum memory.

Researchers from Jiao Tong University discovered that optical moiré lattices can produce solitons — self-trapped solitary waves — at extremely low power levels. The research establishes potential to explore nonlinear phenomena such as four-wave mixing and second-harmonic generation.
