• Detection technique effect on rotational Doppler measurements

  Optics Letters · 2020 · 41 citations

  Senior authorCorresponding

  There are two established methods for measuring rotational Doppler shift: (1) heterodyne and (2) fringe. We identify a key distinction, that only the heterodyne method is sensitive to the rotating object's phase, which results in significant differences in the signal-to-noise ratio (SNR) when measuring multiple rotating particles. When used to measure randomly distributed rotating particles, the fringe method produces its strongest SNR when a single particle is present and its SNR tends to zero…

• Miniaturized widefield microscope for high speed in vivo voltage imaging

  Biomedical Optics Express · 2025-10-30 · 2 citations

  articleOpen access

  Functional imaging in freely moving animals with genetically encoded voltage indicators (GEVIs) will open new capabilities for neuroscientists to study the behavioral relevance of neural activity with high spatial and temporal precision. However, miniaturization of an imaging system with sufficient collection efficiency to resolve the small changes in fluorescence yield from voltage spikes, as well as the development of efficient image sensors that are sufficiently fast to capture them, has prov…

• Impact of mechanically applied strain on Auger recombination in InGaAs multiple quantum wells

  Applied Physics Letters · 2025-01-20 · 2 citations

  articleSenior author

  We present the results of direct measurements of the effect of mechanically applied biaxial strain on Auger recombination rates in InGaAs quantum wells grown on InP. By mounting these structures on a flexible membrane, we applied strain mechanically rather than by changing the quantum well alloy fraction. Specifically, we employed time-resolved photoluminescence spectroscopy to probe the recombination dynamics in the degenerate carrier regime. From these measurements, we extract the non-degenera…

• Wobulation using a tunable electrowetting prism applied to structured illumination microscopy

  Applied Physics Letters · 2025-09-01 · 2 citations

  articleOpen accessSenior author

  Sub-pixel shifting technologies are attractive for enhancing the resolution of cameras and projectors. Conventional techniques, such as wobulation and pixel shift, rely on mechanical moving parts or cumbersome optical systems. As a solution, we demonstrate "electrowetting wobulation," in which a tunable electrowetting prism is used to laterally shift a projected image. This technique overcomes challenges of other pixel shifting techniques, as the electrowetting prism is transmissive, can achieve…
