Optically isotropic longitudinal piezoelectric resonant photoelastic modulator for wide angle polarization modulation at megahertz frequencies
Okan Atalar, Amin Arbabian
Polarization modulators have a broad range of applications in optics. The acceptance angle of a free-space polarization modulator is crucial for many applications. Polarization mod…
Y-Z cut lithium niobate longitudinal piezoelectric resonant photoelastic modulator
Okan Atalar, Steven Yee, Amir H. Safavi-Naeini +1
The capability to modulate the intensity of an optical beam has scientific and practical significance. In this work, we demonstrate Y-Z cut lithium niobate acousto-optic modulators…
Longitudinal piezoelectric resonant photoelastic modulator for efficient intensity modulation at megahertz frequencies
Okan Atalar, Raphaël Van Laer, Amir H. Safavi-Naeini +1
Intensity modulators are an essential component in optics for controlling free-space beams. Many applications require the intensity of a free-space beam to be modulated at a single…
Design and Analysis of a Sample-and-Hold CMOS Electrochemical Sensor for Aptamer-based Therapeutic Drug Monitoring
Jun-Chau Chien, Sam W. Baker, H. Tom Soh +1
In this paper, we present the design and the analysis of an electrochemical circuit for measuring the concentrations of therapeutic drugs using structure-switching aptamers. Aptame…
Design of Large Effective Apertures for Millimeter Wave Systems using a Sparse Array of Subarrays
Anant Gupta, Upamanyu Madhow, Amin Arbabian +1
We investigate synthesis of a large effective aperture using a sparse array of subarrays. We employ a multi-objective optimization framework for placement of subarrays within a pre…
In Vivo Wireless Sensors for Gut Microbiome Redox Monitoring
Spyridon Baltsavias, Will Van Treuren, Marcus J. Weber +4
A perturbed gut microbiome has recently been linked with multiple disease processes, yet researchers currently lack tools that can provide in vivo, quantitative, and real-time insi…
