Abstract: A widely tunable vertical-cavity surface-emitting laser (VCSEL) having a semiconductor cavity followed by an air-gap over which is a movable reflector. Lasing wavelength is controlled by a combination of the resonance of the semiconductor cavity, which is fixed, and the resonance of the air cavity, which can be changed by moving the reflector. Tuning range and slope of the VCSEL are increased by configuring the semiconductor cavity to be antiresonant at the center of the tuning range, which forces electromagnetic energy to be confined more strongly in the air gap than in the semiconductor, thus making emission wavelength more sensitive to the displacement of the tuning mirror.

Abstract: Source identification for unknown molecules using mass spectral matching. In an embodiment, a representation of a query mass spectrum is received in a spectrum query. A repository is searched for the query mass spectrum by, for each of a plurality of reference mass spectra, generating a similarity score between the representation of the query mass spectrum and the representation of the reference mass spectrum, when the similarity score exceeds a predetermined threshold value, without utilizing a molecular identity of a molecule represented by the reference mass spectrum, retrieving metadata associated with the reference mass spectrum, and derive context information from the retrieved metadata, and adding the context information to consensus metadata associated with the query mass spectrum, wherein the context information indicates a source of the reference mass spectrum. The consensus metadata is then returned in response to the spectrum query.

Abstract: Systems, methods, and techniques for optofluidic analyte detection and analysis using multi-mode interference (MMI) waveguides are disclosed herein. In some embodiments, spatially and spectrally multiplexed optical detection of particles is implemented on an optofluidic platform comprising multiple analyte channels intersecting a single MMI waveguide. In some embodiments, multi-stage photonic structures including a first stage MMI waveguide for demultiplexing optical signals by spatially separating different wavelengths of light from one another may be implemented. In some embodiments, a second stage may use single-mode waveguides and/or MMI waveguides to create multi-spot patterns using the demultiplexed, spatially separated light output from the first stage.

Abstract: This disclosure provides a wearable device implemented as a headset such as a virtual reality (VR) headset comprising at least a screen, a gaze tracker, and either one or both the anterior segment or retinal optical coherence tomography and fundus imaging modalities. In some embodiments, the disclosed headset can display a movie on the screen to catch/hold the attention of a patient, and meanwhile capture ocular images of the patient using the ophthalmic imaging modalities in a fully-automated manner. While capturing ophthalmic images, the movie on the screen can cause the patient's gaze to move in various directions in a controllable manner. The gaze tracker can track the movements of the pupils of the patient. The tracked pupil positions can be used to reposition the ophthalmic imaging modalities to refocus and capture images of different regions of the fundus/retina, which allows a widefield-of-view image of the fundus/retina to be reconstructed.

Abstract: A microfluidic device uses hydrodynamic shear forces on a sample to improve the speed and efficiency of tissue digestion is disclosed. The microfluidic channels are designed to apply hydrodynamic shear forces at discrete locations on tissue specimens up to 1 cm in length and 1 mm in diameter, thereby accelerating digestion through hydrodynamic shear forces and improved enzyme-tissue contact. The microfluidic digestion device can eliminate or reduce the need to mince tissue samples with a scalpel, while reducing sample processing time and preserving cell viability. Another advantage is that downstream microfluidic operations could be integrated to enable advanced cell processing and analysis capabilities. The device may be used in research and clinical settings to promote single cell-based analysis technologies, as well as to isolate primary, progenitor, and stem cells for use in the fields of tissue engineering and regenerative medicine.
