A new ultra-energy-efficient tiny laser on a chip could enable powerful medical sensors to fit within a phone, new research finds.The new device is a kind of frequency comb—a specialized laser that generates multiple wavelengths of light, each at a regular frequency interval. On a spectrogram it would look a bit like the teeth of a comb. In the roughly quarter century since they were first developed, these “rulers for light” have revolutionized many kinds of high-precision measurement, from timekeeping to molecular detection. In addition, each line of a comb can be isolated and have properties such as its amplitude modulated to carry data over fiber optics.However, frequency combs typically require bulky, costly, and power-hungry equipment. This has largely limited their use to laboratory settings.Now, scientists at Stanford University employed two different methods that previous work explored to create microchip-scale frequency combs. One strategy, called optical parametric […]

Using 3-D stacks of reflectors on microchips could triple data rates of wireless links to help speed development of 6G communications, a new study finds.Most current wireless communications technology, such as 5G phones, operate at frequencies below 6 gigahertz. For greater data rates, researchers are striving to develop 6G communications that use frequencies above 20 GHz for data rates 100 times great as 5G.However, at 6G‘s anticipated higher frequencies, transmissions also experience greater attenuation and losses from the environment. Thus, instead of depending on a single transmitter and a single receiver, most 5G and 6G technologies use arrays of antennas. These arrays have to precisely control any delay their signals may experience to make sure they arrive when they should and not in a jumble. However, the components involved in adding necessary delays to signals can also usher in problems of their own.The most common delay elements are phase shifters. Although these […]

Wireless spectrum is always at a premium—if you’ve ever tried to connect to Wi-Fi in a crowded airport or stadium, you know the pain that comes from crowded spectrum use. That’s why the industry continues to tinker with ways to get the most out of available spectrum. The latest example: Qualcomm’s FastConnect 7900 chip, which the company unveiled Monday at Mobile World Congress in Barcelona.Qualcomm touts the FastConnect 7900 as a provider of “AI-enhanced” Wi-Fi 7, which the company views as an opportunity to create more reliable wireless connections. The chip will also better integrate the disparate technologies of Wi-Fi, Bluetooth, and ultrawideband for consumer applications. In addition, the chip can support two connections to the same device over the same spectrum band.The FastConnect 7900 comes as the wireless industry renews its focus on reliability with Wi-Fi 7, the wireless tech standard’s latest generation. The emphasis comes in addition improving throughput and […]

In collaboration with Sony, Rohde & Schwarz has successfully validated and verified Sony’s Altair device for its NTN NB-IoT capability. 

The first commercial silicon chip that includes open-source, built-in hardware security was announced today by the OpenTitan coalition.This milestone represents another step in the growth of the open hardware movement. Open hardware has been gaining steam since the development of the popular open-source processor architecture RISC-V. RISC-V gives an openly available prescription for how a computer can operate efficiently at the most basic level. (The acronym RISC stands for reduced instruction set computer and, as a less-is-more approach to computer architecture, traces back to the late 1970s.) OpenTitan goes beyond RISC-V’s open-source instruction set by delivering an open-source design for the silicon itself. Although other open-source silicon has been developed, this is the first one to include the design-verification stage and to produce a fully functional commercial chip, the coalition claims.Utilizing a RISC-V based processor core, the chip, called Earl Grey, includes a number […]
