Readout of Superconducting Nanowire Single Photon Detectors through Forward Biased Optical Modulators
Marc de Cea, Emma E. Wollman, Amir H. Atabaki +3
Scalable, high speed data transfer between cryogenic (0.1-4 K) and room temperature environments is instrumental in a broad range of fields including quantum computing, superconduc…
Compact and high-precision wavemeters using the Talbot effect and signal processing
Ningren Han, Gavin N. West, Amir H. Atabaki +2
Precise knowledge of a laser's wavelength is crucial for applications from spectroscopy to telecommunications. Here we present a wavemeter which operates on the Talbot effect. Tone…
Low-loss integrated photonics for the blue and ultraviolet regime
Gavin N. West, William Loh, Dave Kharas +5
We present a low-loss integrated photonics platform in the visible and near ultraviolet regime. Fully-etched waveguides based on atomic layer deposition (ALD) of aluminum oxide ope…
Bayesian Modeling and Computation for Analyte Quantification in Complex Mixtures Using Raman Spectroscopy
Ningren Han, Rajeev J. Ram
In this work, we propose a two-stage algorithm based on Bayesian modeling and computation aiming at quantifying analyte concentrations or quantities in complex mixtures with Raman…
Precise and diffraction-limited waveguide-to-free-space focusing gratings
Karan K. Mehta, Rajeev J. Ram
We present the design and characterization of waveguide grating devices that couple visible-wavelength light at nm from single-mode, high index-contrast dielectric waveguid…
Infrared vertically-illuminated photodiode for chip alignment feedback
Luca Alloatti, Rajeev Jagga Ram
We report on vertically-illuminated photodiodes fabricated in the GlobalFoundries 45nm 12SOI node and on a packaging concept for optically-interconnected chips. The photodiodes are…
