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 ...

Radio telescopes are instruments that capture faint radio signals from space and convert them into images of celestial bodies ...

(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) ...

Optical frequency comb technology and its capability to directly measure and convert optical frequencies has revolutionized the field of high-precision metrology. While it is enabling novel ...

A team has developed an electro-optic frequency comb that is 100-times more efficient and has more than twice the bandwidth of previous state-of-the-art versions. On-chip laser frequency combs -- ...

It may seem at times that there is a divide between the optical/photonic domain and the RF one, with the terahertz zone between them as a demarcation. If you need to make a transition between the ...

NTT Corp. (NTT) and Tokyo Denki University, both based in Japan, have succeeded in further stabilizing the output of an optical frequency ruler generated by modulating the intensity and phase of laser ...
