    Abstract: An optical amplifier (fig. 3) comprises a trivalent thulium-doped optical fiber (120): a first pump light emitting device (110) optically coupled to the fiber for generating a primary pump source at a first wavelength, and a second pump light (180) emitting device optically coupled to the fiber (120) for generating a secondary pump source at a second wavelength. In a preferred aspect of the present invention, the amplifier also includes a third (auxiliary) pump light emitting device (130) optically coupled to the fiber (120) for generating a third pump source at a third wavelength. Each of the amplification signals comprise at least one pre-selected wavelength. The first amplification signal has a wavelength pre-selected to provide a reduced noise figure for the amplifier. The second amplification signal has a wavelength pre-selected to increase the optical efficiency of the amplifier. The third amplification signal can have a wavelength pre-selected to populate the 3F4 energy level of the fiber, and to minimize depletion of the 3H6 ground state.

    Abstract: A surface plasmon resonance sensor system including a high refractive index prism, a sensor chip, a light source having multiple wavelengths over a broad range of wavelengths, optical lenses, a photodetector, a data acquisition unit, and as defined herein. The sensor chip can include, for example, a thin layer of silicon and gold on one face of a transparent substrate and the prism adjacent to the opposite face of the transparent substrate. Such an arrangement provides variable penetration depths up to about 1.5 micrometers with a dynamic range for sensing index of refraction changes in a sample that are several times greater than that of a conventional SPR sensor. The disclosure provides methods for using the surface plasmon resonance sensor system for cell assay or chemical assay related applications.

The inner cladding (32) has an inner cladding refractive index less than the core refractive index, an inner cladding cross-sectional area between 2 and 25 times greater than that of the core cross-sectional area, and an aspect ratio greater than 1.5:1. An outer cladding (36) surrounds the inner cladding (32) and has an outer cladding refractive index less than the inner cladding refractive index.
