Comb-Based Radio-Frequency Photonic Filters with Rapid Tunability and High Selectivity
V. R. Supradeepa, Christopher M. Long, Rui Wu +4
Photonic technologies have received considerable attention for enhancement of radio-frequency (RF) electrical systems, including high-frequency analog signal transmission, control…
Gaussian-shaped Optical Frequency Comb Generation for Microwave Photonic Filtering
Rui Wu, Christopher M. Long, Ehsan Hamidi +4
Using only electro-optic modulators, we generate a 41-line 10-GHz Gaussian-shaped optical frequency comb. We use this comb to demonstrate apodized microwave photonic filters with g…
Generation of very flat optical frequency combs from continuous-wave lasers using cascaded intensity and phase modulators driven by tailored radio frequency waveforms
Rui Wu, V. R. Supradeepa, Christopher M. Long +2
We demonstrate a scheme, based on a cascade of lithium niobate intensity and phase modulators driven by specially tailored radio frequency waveforms to generate an optical frequenc…
Self-referenced characterization of optical frequency combs and arbitrary waveforms using a simple, linear, zero-delay implementation of spectral shearing interferometry
V. R. Supradeepa, Christopher M. Long, Daniel E. Leaird +1
We discuss a simple, linear, zero-delay implementation of spectral shearing interferometry for amplitude and phase characterization of optical frequency comb sources and arbitrary…
Fast Characterization of Dispersion and Dispersion Slope of Optical Fiber Links using Spectral Interferometry with Frequency Combs
V. R. Supradeepa, Christopher M. Long, Daniel E. Leaird +1
We demonstrate fast characterization (~1.4 microseconds) of both the dispersion and dispersion slope of long optical fiber links (~25 km) using dual quadrature spectral interferome…
