摘要： A sensing device that produces a Raman signal includes micro-rods or nano-rods arranged on a substrate in a two-dimensional (2D) array, each of the rods having a length in a single row being substantially the same, with the rod length of each row being different from the rod length of each other row. Each row of rods has a respective resonant vibration frequency that varies from row to row. A source of vibration energy, operatively connected to the substrate, excites vibration in each of the rods such that a responding row resonates when an exciting frequency approaches the resonant vibration frequency of the responding row. A method includes exposing the 2D array to a light source and analyzing Raman scattering at each rod of the 2D array to render a Raman map.

摘要： A fast injection optical switch is disclosed. The optical switch includes a thyristor having a plurality of layers including an outer doped layer and a switching layer. An area of the thyristor is configured to receive a light beam to be directed through at least one of the plurality of layers and exit the thyristor at a predetermined angle. At least two electrodes are coupled to the thyristor and configured to enable a voltage to be applied to facilitate carriers from the outer doped layer to be directed to the switching layer. Sufficient carriers can be directed to the switching layer to provide a change in refractive index of the switching layer to redirect at least a portion of the light beam to exit the thyristor at a deflection angle different from the predetermined angle.
