    摘要： A nano-colonnade VCSEL device and a method of fabrication utilize a nanowire column grown nearly vertically from a (111) horizontal surface of a first layer to another horizontal surface of a second layer to connect the layers. The VCSEL device includes a first layer having the (111) horizontal surface; a second layer; and an insulator support between the first layer and the second layer that separates the first layer from the second layer. A portion of the second layer overhangs the insulator support, such that a horizontal surface of the overhanging portion is spaced from and faces the (111) horizontal surface of the first layer. The VCSEL device further includes a nanowire column extending nearly vertically from the (111) horizontal surface to the facing horizontal surface, and distributed Bragg mirrors adjacent to opposite end of the nanowire column.

    摘要： Light sources that use diamond nanowires, and methods of forming the same, are described. For example, the light source can include a diamond nanowire that bridges the gap between a first electrode and a second electrode to electrically couple the two electrodes. A power source coupled to the first and second electrodes forms a circuit. The diamond nanowire emits light with the power source turned on.

    摘要： Devices, systems, and methods using Surface Enhanced Raman Spectroscopy (SERS) are disclosed. A device for generating Raman scattered radiation comprises a laser source and a SERS-active structure. The laser source may be configured for emanating radiation from an emanating surface or by forming a depression in the laser source, which creates a region of increased evanescent field from the laser source. SERS systems and methods include a device for generating Raman scattered radiation with a detector configured to receive the Raman scattered radiation.
