    Abstract: Devices, systems, and methods for enhancing Raman spectroscopy and hyper-Raman are disclosed. A molecular analysis device for performing Raman spectroscopy comprises a substrate and a laser source disposed on the substrate. The laser source may be configured for emanating a laser radiation, which may irradiate an analyte disposed on a Raman enhancement structure. The Raman enhancement structure may be disposed in a waveguide. The molecular analysis device also includes a wavelength demultiplexer and radiation sensors disposed on the substrate and configured for receiving a Raman scattered radiation, which may be generated by the irradiation of the analyte and Raman enhancement structure.

    Abstract: An apparatus for sensing at least one property of a fluid is described. A first photonic crystal structure and a second photonic crystal structure are defined in a dielectric slab. The first and second photonic crystal structures comprise differently patterned arrays of channels extending through the dielectric slab. The apparatus further comprises a fluid introduction device configured to introduce a common volume of the fluid into the channels of the first and second photonic crystal structures. The at least one property of the fluid can be sensed by measuring the propagation of radiation through the first and second photonic crystal structures.

    Abstract: An optical sensor is provided, comprising (a) a silicon nanowire of finite length having an electrical contact pad at each end thereof; and (b) a plurality of self-assembled molecules on a surface of the silicon nanowire, the molecules serving to modulate electrical conductivity of the silicon nanowire by either a reversible change in dipole moment of the molecules or by a reversible molecule-assisted electron/energy transfer from the molecules onto the silicon nanowire. Further, a method of making the optical sensor is provided. The concept of molecular self-assembly is applied in attaching functional molecules onto silicon nanowire surfaces, and the requirement of molecule modification (hydroxy group in molecules) is minimal from the point view of synthetic difficulty and compatibility. Self-assembly will produce well-ordered ultra-thin films with strong chemical bonding on a surface that cannot be easily achieved by other conventional methods.
