High-power 150 mW extended cavity Si3N4 tunable narrow-linewidth laser
Chilas develops off-the-shelf laser sources based on hybrid integration of Photonic Integrated Chips (PICs). Combining the high optical powers of semiconducting optical amplifiers (SOAs) with low-loss wavelength tunable mirror structures on Si3N4 PICs results in compact and robust tunable laser sources.
Light-field ghost imaging
Techniques based on classical and quantum correlations in light beams, such as ghost imaging, allow us to overcome many limitations of conventional imaging and sensing protocols.
Multiparameter quantum sensing and magnetic communication with a hybrid dc/rf optically pumped magnetometer
We introduce and demonstrate a hybrid optically-pumped magnetometer (hOPM) that simultaneously measures one dc field component and one rf field component quadrature with a single atomic spin ensemble.
Quantum-Enhanced Magnetometry at Optimal Number Density
We study the use of squeezed probe light and evasion of measurement backaction to enhance the sensitvity and measurement bandwith of an optically pumped magnetometer (OPM) at sensitivity-optimal atom number density. By experimental observation, and in agreement with quantum noise modeling, a spin-exchange-limited OPM proved with off-resonance laser light is shown to have an optimal sensitivity determined by density-dependent quantum noise contributions.
Deep learning approach for denoising low-SNR correlation plenoptic images
Correlation Plenoptic Imaging (CPI) is a novel volumetric imaging technique that uses two sensors and the spatio-temporal correlations of light to detect both the spatial distribution and the direction of light.
