We propose and experimentally demonstrate an all-fiber reconfigurable comb spacing multiplier based on parametric and Raman-assisted spectral Talbot effect. In proof-of-concept experiments, our method ...

A research group led by Professor Lilin Yi from the State Key Lab of Advanced Systems and Networks at Shanghai Jiao Tong ...

Optical frequency combs—which emit thousands of regularly spaced spectral lines—have transformed fields like metrology, spectroscopy and precision timekeeping via optical atomic clocks ...

A device called an all-optical switch could instead use light to control other light signals without the need for electrical conversion, saving both time and energy in fiber-optic communication. A ...

T he invention of optical frequency combs revolutionized frequency metrology and time-keeping. Miniaturization of such combs onto photonic chips, primarily leveraging the microresonator Kerr ...

Optical frequency combs — a type of laser that emits thousands of regularly spaced spectral lines — have transformed fields like metrology, spectroscopy and precision timekeeping via optical ...

Abstract: A segmental method utilizing a pre-definable electro-optic frequency comb (EOFC) is proposed for characterizing the frequency response of high-speed photodiodes (PDs). The EOFC is generated ...
