For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment TOKYO--(BUSINESS WIRE)--NTT Corporation (NTT) and ...

Optical frequency combs have revolutionized technologies such as atomic clocks, spectroscopy, and ultra-fast lasers by acting as precise bridges between optical and microwave frequencies. As the ...

Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for precision measurement, found in optical clocks, gas-sensing spectrometers, and ...

(Nanowerk News) Optical frequency comb (OFC) provides equidistant comb lines in broad bandwidth, and each comb line corresponds to an absolute optical frequency, which is similar as a comb (or rule) ...

Nature has a way of finding optimal solutions to complex problems. For example, despite the billions of ways for a single protein to fold, proteins always fold in a way that minimizes potential energy ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Researchers have developed a device that can detect the presence of specific molecules in a sample every 20 nanoseconds, or billionths of a second. With this new capability, researchers can ...

Since the conception of the laser frequency comb in the late 1990s, it has revolutionized the precise measurement of frequency and time. Beyond their initial use in optical clocks and precision ...
