A research team led by MIT has developed anovel piece of kit that can drastically increase the speed and capability of optical beam forming technology and that’s easy to produce at scale.<\/p>\n

If commercialized, the team’s new type of spatial light modulator (SLM) could open the way to super-fast LiDAR imaging for autonomous vehicles, improved medical scanners and even developing free-standing 3D holograms akin to those from Star Wars.\u00a0Admittedly we’ll be waiting on that last one for a while.<\/p>\n

According to MIT, the project has been a four-year endeavor<\/a> leading up to a paper<\/a> published in Nature<\/em> this week. Lead author Dr Christopher Panuski described the findings as a “major step toward the ultimate goal of complete optical control \u2014 in both space and time \u2014 for the myriad applications that use light.”\u00a0<\/p>\n

An SLM upgrade<\/h3>\n

SLMs are devices that modulate the wavelengths of beams of light to produce colors or shapes; the most basic example of this is the overhead projector transparency sheet.\u00a0<\/p>\n

More advanced SLMs use two-dimensional arrays of things like liquid crystals and digital micromirrors to change the colors of light passing through them, but those are still limited in bandwidth and pixel density. To get around these limitations, the MIT team opted for an array of “photonic crystal microcavities” they call a PhC-SLM. According to the researchers, their design achieves a ten-fold improvement over older 2D SLMs.\u00a0<\/p>\n
