From broadband biphotons to frequency combs via spectral compression with time-varying cavities Open
Biphoton frequency combs are promising resources for quantum networking due in large part to their compatibility with the telecommunication infrastructure. In this work, we propose a method to periodically compress broadband frequency-enta…

Quantum nonlocal modulation cancelation with distributed clocks Open
We demonstrate nonlocal modulation of entangled photons with truly distributed radio frequency (RF) clocks. Leveraging a custom radio-over-fiber (RFoF) system characterized via classical spectral interference, we validate its effectiveness…

High-speed RF spectral analysis using a Rayleigh backscattering speckle spectrometer Open
Persistent wideband radio frequency (RF) surveillance and spectral analysis is increasingly important, driven by the proliferation of wireless communication and RADAR technology. However, conventional electronic approaches are limited by t…

Architecture for integrated RF photonic downconversion of electronic signals Open
Electronic analog to digital converters (ADCs) are running up against the well-known bit depth versus bandwidth trade off. Towards this end, radio frequency (RF) photonic-enhanced ADCs have been the subject of interest for some time. Optic…

High-resolution wide-band optical frequency comb control using stimulated Brillouin scattering Open
We introduce a technique to manipulate an optical frequency comb on a line-by-line basis using stimulated Brillouin scattering (SBS). The narrow-linewidth SBS process has been used to address individual lines in optical frequency combs, bu…

Impact of Nonlinearity Including Bleaching in $p$-$i$-$n$ Photodetectors on RF-Modulated Electro-Optic Frequency Combs Open
We use a drift-diffusion model that includes the effect of bleaching to study the impact of nonlinear distortion in a -- photodetector (PD) on RF-modulated frequency combs. This work complements a similar study that we carried out for a mo…

Impact of nonlinearity including bleaching in MUTC photodetectors on RF-modulated electro-optic frequency combs Open
We use the drift-diffusion equations to calculate the responsivity of a modified uni-traveling carrier (MUTC) photodetector (PD) with a frequency comb input that is generated by a series of short optical pulses. We first use experimental r…

Characterization of 107 Genomic DNA Reference Materials for CYP2D6, CYP2C19, CYP2C9, VKORC1, and UGT1A1: A GeT-RM and Association for Molecular Pathology Collaborative Project Open
Pharmacogenetic testing is becoming more common; however, very few quality control and other reference materials that cover alleles commonly included in such assays are currently available. To address these needs, the Centers for Disease C…

Impact on frequency combs of nonlinearity including bleaching in p-i-n photodetectors Open
We calculate the impact of nonlinearity in a p-i-n photodetector on an RF-modulated frequency comb taking into account bleaching due to the large peak-to-average power ratio in frequency combs. We characterized RF-modulated frequency combs…

Impact of Nonlinearity on RF-Modulated Frequency Combs with Different Modulation Depths in an MUTC Photodetector Open
We calculate the impact of nonlinearity in a modified uni-traveling carrier (MUTC) photodetector on an RF-modulated frequency comb that is generated using short optical pulses. We take into account bleaching (nonlinear saturation), which p…

Calculation of the impulse response and phase noise of a high-current photodetector using the drift-diffusion equations Open
We describe a procedure to calculate the impulse response and phase noise of high-current photodetectors using the drift-diffusion equations while avoiding computationally expensive Monte Carlo simulations. We apply this procedure to a mod…

Non-Uniform Sub-Nyquist Optical Sampling by Acousto-Optic Delay Modulation Open
This paper presents an optical sampler based on the combination of a mode-locked laser and external acousto-optic delay modulator, and demonstrates its use in a non-uniformly subsampled photonic link. Delay modulation of the laser's unifor…

Characterization of a Downconverting, Phase-Modulated RF-Over-Fiber Link With a Single Modulator Open
We present and fully characterize a downconverting RF-over-fiber link that uses one dual-RF drive Mach–Zehnder modulator as a phase modulator. One RF input presents the signal and the other input presents the local oscillator to the modula…
