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 ...

Illustration of a Raman-suppressed, X-cut thin film lithium niobate racetrack microresonator used for microcomb generation. Harvard researchers have demonstrated a special type of optical frequency ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have discovered a new way to generate ultra-precise, evenly spaced "combs" of laser light on a ...

Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...
