  • Strain tuning individual quantum dot emission frequencies with local phase transitions
    Patent number: 11150495
    Abstract: A technique is described to deterministically tune the emission frequency of individual semiconductor photon sources, for example quantum dots. A focused laser is directed at a film of material that changes form when heated (for example, a phase change material that undergoes change between crystal and amorphous forms) overlaid on a photonic membrane that includes the photon sources. The laser causes a localized change in form in the film, resulting in a change in emission frequency of a photon source.

  • Protease transducers and sensors based on DNA loops
    Patent number: 11150186
    Abstract: The stiffness and topology of ultra-small circular DNAs and DNA/peptide hybrids are exploited to create a transducer of enzyme activity with low error rates. The modularity and flexibility of the concept are illustrated by demonstrating various transducers that respond to either specific restriction endonucleases or to specific proteases. In all cases the output is a DNA oligo signal that, as we show, can readily be converted directly to an optical readout, or can serve as input for further processing, for example, using DNA logic or amplification. By exploiting the DNA hairpin (or stem-loop) structure and the phenomenon of strand displacement, an enzyme signal is converted into a DNA signal, in the manner of a transducer. This is valuable because a DNA signal can be readily amplified, combined, and processed as information.

  • Diamond on nanopatterned substrate
    Patent number: 11131039
    Abstract: A method for growing polycrystalline diamond films having engineered grain growth and microstructure.

  • Highly stable semiconductor lasers and sensors for III-V and silicon photonic integrated circuits
    Patent number: 11125689
    Abstract: Building blocks are provided for on-chip chemical sensors and other highly-compact photonic integrated circuits combining interband or quantum cascade lasers and detectors with passive waveguides and other components integrated on a III-V or silicon. A MWIR or LWIR laser source is evanescently coupled into a passive extended or resonant-cavity waveguide that provides evanescent coupling to a sample gas (or liquid) for spectroscopic chemical sensing. In the case of an ICL, the uppermost layer of this passive waveguide has a relatively high index of refraction that enables it to form the core of the waveguide, while the ambient air, consisting of the sample gas, functions as the top cladding layer. A fraction of the propagating light beam is absorbed by the sample gas if it contains a chemical species having a fingerprint absorption feature within the spectral linewidth of the laser emission.
