We study quasi-bound states in the continuum with diverging resonance lifetime and vanishing resonant linewidth in a novel double-sided grating metamaterial. With rigorous computations, we corroborate that specific physical conditions are required to obtain the diverging resonance quality factor.

This work presents III-V strained layer superlattice (SLS) detectors with an emphasis on InGaAs/InAsSb SLS designs. Compared to conventional InAs/In(Ga)Sb and InAs/InAsSb designs, InGaAs/InAsSb enables a wider design space for performance improvements. Various SLS designs and experimental results are provided and discussed.

Optical metamaterials can achieve optical performance specifications otherwise unattainable compared to their bulk constituents via the use of skillfully engineered nanoscale features. These features function as sub-wavelength optical scatterers, causing incident light to interact with metamaterials in a manner which is crucially dependent on their geometry. To design the next generation of functional materials, scientists and engineers must realize new methods which prudently explore the near-infinite number of possible metamaterial arrangements. We present a general methodology which harnesses machine learning to accelerate the process of metamaterial design and apply it specifically here, as a test case, to a silicon on insulator (SOI) reflective metasurface consisting of an array of nano-pillars. In particular, we implement artificial neural networks (ANNs) to solve the inverse design problem; i.e. we prescribe a desired reflection profile and utilize ANNs to advise what metasurface array of SOI nano-pillars gives the closest result. Utilizing a synthetic data set of devices simulated with rigorous coupled wave analysis (RCWA), we create an ANN-accelerated simulator, achieving a computational speedup of O(106) over the relatively quick RCWA simulation method. We then couple this simulator with an ANN-based predictor, which directly binds the SOI metasurfaces in question to a targeted optical performance. Together, this simulator/predictor ANNs combination provides a general framework in rapidly evaluating and designing potential optical metamaterial devices beyond what is currently possible via straightforward simulation and more standard optimization methods.

The polarization of objects relevant to remote sensing imaged with midwave and longwave infrared passive polarimetrie sensors is not intuitive due to the multiple variables influencing polarization. We analyze polarization for varying conditions and compare simulated data with measurements collected in laboratory and field experiments.

Bandgap and carrier dispersion in superlattices (SL) based on InAsSb can be precisely controlled by variation of the layer composition and width. However, when grown strain-balanced on GaSb, possible SL designs are seriously limited. The virtual substrate approach on the other hand removes this limitation thus opening a way to design SLs and QWs with non-generic electronic properties including Dirac carrier dispersion and topologically nontrivial states.

Biomarker testing is the first step toward diagnosis of many diseases including cancer, cardiovascular and infections. In addition to traditional circulating biomarkers such as protein, DNA and RNA, microRNAs (miRNAs) could also be used to accurately map the disease related biological changes at tissue, organ or cellular level. One of the roadblocks for using miRNA in diagnosis is the accurate detection of panel of miRNA biomarkers in clinical samples. Current detection methods are expensive, lacking sensitivity and specificity for clinical samples. In addition, to minimize the degradation, miRNA need to be detected within 30 min of sample collection and current detection methods will take hours to days. To address this critical issue, we have developed a new method where we used molecular-field interactions to concentrate target miRNA near micro-electrodes in the disposable device. We then used electrical impedance to quantify the target miRNAs. Our results show that proposed method could detect miRNAs that are in pico-molar levels.

Room-temperature microbolometer arrays with sensitivity in narrow wavelength bands for spectral imaging in the mid-wave and long-wave infrared are described. The approach is based on vanadium-oxide air-bridge bolometers that are integrated with plasmonic resonant absorbers to maintain response speed without adding processing complexity.
