Abstract: Devices, systems, and methods of using one or more memristors as a radiation sensor are enabled. A memristor can be attractive as a sensor due to its passive low power characteristics. Medical and environment monitoring are contemplated use cases. Sensing radiation as part of a security system (at an airport for example) and screening food for radiation exposure are also possible uses. The memristor as a radiation sensor may possibly provide an inexpensive and easy alternative to personal thermoluminescent dosimeters (TLD). Memristor devices with high current and low power operation may be attached with wearable plastic substrates. An example device includes two metal strips with a 50 μm thick layer of TiO2 memristor material. The device may be made large relative to traditional memristors which are nanometers in scale but its increased thickness can significantly increase the probability of radiation interaction with the memristor material.

Abstract: Embodiments include a fiber optic probe comprising an optical fiber, and a sensor component attached to the optical fiber, the sensor component including an asymmetric microlens array imprinted on a stimuli-responsive hydrogel. Embodiments further include a method of fabricating a fiber optic probe comprising depositing a stimuli-responsive hydrogel precursor solution on a substrate mold, the substrate mold including a concave asymmetric microlens array; contacting an end of an optical fiber with the stimuli-responsive hydrogel precursor solution deposited on the substrate mold; and exposing the end of the optical fiber and the stimuli-responsive hydrogel precursor solution to light to form a stimuli-responsive hydrogel sensor imprinted with a convex asymmetric microlens array and attached to the end of the optical fiber. Embodiments further include systems comprising the fiber optic probes.

Abstract: Structures for a waveguide crossing and methods of fabricating a structure for a waveguide crossing. A waveguide crossing includes a central section and an arm positioned between a waveguide core and the central section. The arm and the waveguide core are aligned along a longitudinal axis. The arm is coupled to the waveguide core at a first interface, and the arm is coupled to a portion of the central section at a second interface. The arm has a first width at the first interface, a second width at the second interface, and a third width between the first interface and the second interface. The third width is greater than either the first width or the second width.
