Designing a Silicon Photonic MEMS Phase Shifter with Simulation

Existing infrastructure still relies on many electrical signal processing components embedded inside fiber optic networks.

Meta Optical Elements

The size and complexity of lens systems can be reduced through flat optics that are based on pioneering meta optical elements (MOEs).

Time-of-Flight: Highly Reliable 3D Imaging for Challenging Applications

There are multiple technologies based on the ToF concept. Generally, all of them are synchronized with a light source and estimate the distance by calculating the time taken for the light to travel from the camera to the object and then back again.

Challenges of Fabricating and Coating Laser Crystals

Because laser crystals are sensitive optical components and are often used with high-power lasers, depositing the correct coatings onto them without introducing any defects is essential.

Designing a Human-Robot Collaboration System

Scientists analyzed the stability of the collaborative system based on speed and accuracy, as well as the conditions required for successfully performing tasks from geometric, force, and posture viewpoints.

New Technology Could Make Biopsies a Thing of the Past

MediSCAPE is a highspeed 3D microscope capable of capturing images of tissue structures that could guide surgeons to navigate tumors and their boundaries without needing to remove tissues and wait for pathology results.

Rice ‘Metalens’ Could Disrupt Vacuum UV Market

Tests showed the metalens they made could focus its 197-nanometer output onto a spot measuring 1.7 microns in diameter, increasing the power density of the light output by 21 times.

Upside-Down Design Expands Wide-Spectrum Super-Camera Abilities

Plasmonics is a technology that essentially traps the energy of light in groups of electrons oscillating together on a metal surface.

Researchers Demonstrate 40-Channel Optical Communication Link

It achieves 40 channels by combining a frequency comb light source based on a new photonic crystal resonator developed by the National Institute of Standards and Technology (NIST) with an optimized mode-division multiplexer.
