Today, machine learning based methods are of our everyday life, with millions of users every day unlocking their phones through facial recognition or passing through AI-enabled automated security checks at airports and train stations. Traditionally, the processing of information native to the optical domain is being executed in the electronic domain, requiring energy-hungry specialized electronic hardware and conversion between the two realms. Optical machine learning is emerging as an important field, where the processing of optical information is done directly within the optical domain, power-efficient and at the spe ....

WASHINGTON Researchers have developed a noninvasive technique that can capture images of rod and cone photoreceptors with unprecedented detail. The advance could lead to new treatments and earlier detection for retinal diseases such as macular degeneration, a leading cause of vision loss.
We are hopeful that this technique will better reveal subtle changes in the size, shape and distribution of rod and cone photoreceptors in diseases that affect the retina, said research team leader Johnny Tam from the National Eye Institute. Figuring out what happens to these cells before they are lost is an important step toward developing earlier interventions to treat and prev ....

Polarization control is essential for tailoring light-matter interactions and is the foundation for many applications such as polarization imaging, nonlinear optics, data storage, and information multiplexing. A linear polarizer, which is a polarization optical element that filters a specific linear polarization from unpolarized light, plays an important role in both polarization generation and manipulation. However, the generation of arbitrary polarization states other than linear polarization usually requires cascading of multiple optical polarization elements, including both linear polarizers and wavepla ....

Spatiotemporal metasurfaces, driven by ultrafast dynamic modulations, opened up new possibilities for manipulating the harmonic modes of electromagnetic waves and generations of exotic physical phenomena, such as dispersion cancellation, Lorentz reciprocity broken, and Doppler illusions. In recent years, rapid development of information technologies have stimulated many information processing applications for metasurfaces, including computational imaging, wireless communications, and performing mathematical operations. With increasing amount of researches focused on the topic of information processing with metasurfaces, a gen ....

Lithium niobate crystal film for integrated photonic applications

Credit: by Hong Liu
In contemporary society, the demand for high-bandwidth optical communication, including mobile high-definition videos, autonomous vehicles, remote surgery, telepresence, and interactive 3D virtual reality gaming, is sharply increasing. The electro-optical modulator is the key component for optical fiber communication, which modulates the light signal for loading information through electricity. Lithium niobate (LiNbO3, LN) exhibits a high-performance electro-optic effect and high optical transparency. On the other hand, the ferroelectric domain engineering on LN crystals has been extended from 1D to 2D and 3D. Moreover, considering the device size, reliability, cost, and energy consumption, the photonic integrated circuit (PIC) technology has recently gained signi?cant interest in the rise of the integrated photonics field. Integrated photonics is concerned with the integration of all the key components connected by a waveguide in a single chip (photonic pl ....
