The team from the UCLA Henry Samueli School of Engineering and Applied Science developed a specialized artificial material, a type of “metasurface,” that can tune the laser’s polarization state purely electronically, without any moving parts. The research was published in Optica. The breakthrough advance was applied to a class of lasers in the terahertz range of frequencies on the electromagnetic spectrum, which lies between microwaves and infrared waves.

The lead authors of the research are electrical engineering graduate student Luyao Xu and electrical engineering undergraduate student Daguan Chen. Other authors include electrical engineering graduate student Christopher Curwen; Mohammad Memarian, a postdoctoral scholar in UCLA’s microwave electronics lab; John Reno of Sandia National Laboratories; and UCLA electrical engineering professor Tatsuo Itoh, who holds the Northrop Grumman Chair in Engineering.

“While there are a few ways to quickly switch polarization in the visible spectrum, in the terahertz range there is currently a lack of good options,” said Benjamin Williams, associate professor of electrical engineering and the principal investigator of the research. “In our approach, the polarization control is built right into the laser itself. This allows a more compact and integrated setup, as well as the possibility for very fast electronic switching of the polarization. Also, our laser efficiently generates the light into the desired polarization state — no laser power is wasted generating light in the wrong polarization.”

The 35mm lens can attach to an M4/3 mirrorless camera and fit onto an APS-C mirrorless camera with a selection of E, EF-M, and Z lens mounts by attaching the optional adapter rings.

Terahertz radiation penetrates many materials, such as dielectric coatings, paints, foams, plastics, packaging materials, and more without damaging them, Williams said.

As users adjust the aperture, the unique light streaks and star burst will adapt to the aperture value for the optimum cinematic visual effect.

“So some applications include non-destructive evaluation in industrial settings, or revealing hidden features in the study of art and antiquities,” said Williams, who directs the Terahertz Devices and Intersubband Nanostructures Laboratory. “For example, our laser could be used for terahertz imaging, where the addition of polarization contrast may help to uncover additional information in artwork, such as improved edge detection for hidden defects or structures.”

Their new metasurface covers an area of 2 square millimeters and has a distinct zigzag pattern of wire antennas running across its surface. An electric current runs through the wires, selectively energizing particular segments of the laser material, which allows a user to change and customize the polarization state as needed.

When shooting with a compatible camera, the 35mm F1.8 Anamorphic Lens uses its 1.33x squeeze factor to widen the horizontal field of view and produce a wider, full HD 2.4:1 cinematic video without any post-cropping.

Due to the 1.33x squeeze factor, the round light spots in the background will de-squeeze into an enchanting oval bokeh, which couples with the foreground for an aesthetic upgrade.

Due to the popularity of cinematic aesthetics, photographers and shutterbugs usually convert a 16:9 camera shot into a 2.4:1 cinematic aspect ratio via post-editing applications. Although this method achieves a cinematic look, it also degrades the footage and results in lower quality images.

Like brightness and color, polarization is a fundamental property of light that emerges from a laser. The traditional way to control the polarization of a laser was to use a separate component like a polarizer or a waveplate. To change its polarization, the polarizer or waveplate must be physically rotated, a slow process that results in a physically larger laser system.

A research team led by UCLA electrical engineers has developed a new technique to control the polarization state of a laser that could lead to a new class of powerful, high-quality lasers for use in medical imaging, chemical sensing and detection, or fundamental science research.

The MFT-mount 35mm f/1.8 Anamorphic 1.33x Lens from Sirui is designed for MFT/APS-C cameras and increases the horizontal FOV by 33% in comparison with traditional 35mm APS-C lenses. The result is equivalent to a wider 26.3mm APS-C lens.

Special in its anamorphic structure and multilayer Nano-coatings, this 35mm lens softens and controls lights within a scene using the special function, Sci-Fi Blue Light Streaks with Pleasing Star Burst.

Compared to general camera lenses, the SIRUI 35mm F1.8 1.33x Anamorphic Lens can easily produce a cinematic widescreen look for users without post-cropping or using additional tools to highlight their creative shots.

Think of polarized sunglasses, which help people see more clearly in intense light. Polarizing works by filtering visible light waves to allow only waves that have their electric field pointing in one specific direction to pass through, which reduces brightness and glare.

Eye your scenes through the lens and revive their beauty by adjusting the light setting between the F/1.8 and F/16 apertures. Even wide open at F/1.8, this lens can still produce sharp, quality imaging with a smooth depth of field when targeting the subject/object using the 35mm focal length.
