The levitated laser dye droplet was optically pumped by a pulsed (pulse length 5 ns, repetition rate 10 Hz), frequency-doubled Nd YAG laser (2 = 532 nm) in free-space optical setup. Droplet light emission was collected by a multimode optical fiber placed at an angle of approximately 50° relative to pump laser beam. Collected light was analyzed in a fixed-grating spectrometer with a resolution of FWHM 0.15 nm.

Multilayer Langmuir-Blodgett films doped with a cyanine dye have been deposited on the surface of a quartz multimode optical fiber and the fluorescence properties investigated. 49 The fluorescence intensity of the films was found to be a periodic function of the number of layers due to the waveguide properties of the films. 

In the case of multimode optical fibers a well defined radial variation of dope concentration in the fiber core is required for high data transmission capacity. Therefore...

The scattering of evanescent waves by an individual GNP is shown in Figure 8.9. As assumed in the experimental setup, the core of a multimode optical fiber is simplified as a semi-infinite dielectric plane medium because the radius of... 

The optical flber SPR is the smaller device of this technology, allowing the use of this technique in distant locations. Sensors based on monomode and multimode optical flbers have been reported [23,24]. The cladding of the flber is partially removed and a gold layer is deposited symmetrically around the exposed fiber core. This type of fabrication limits the interaction area to a... 

Sensors and other devices were developed on optical fibers by incorporating metallic and semiconducting nanoparticles on the surface of optical fibers. Several ways of forming sensitive and robust chemical sensors based on plasmon resonances of metallic islands and nanoparticles were demonstrated. Development of in-line optical fiber stractmes, involving single mode or multimode optical fibers fused to an arrangement of coreless... 

Figure 7.3a is a photograph of the assembled microchip device. Two pairs of multimode optic fibers were integrated with the plastic chip to facilitate multiple wavelength detection of two different types of fluorescence dyes. 

Typically, modal dispersion is the dominant factor degrading the bandwidth for multimode optical fibers such as SI POFs. However, as mentioned above, it can be minimized by forming a quadratic refractive index profile in the core region and controlling the propagation speed of each mode. This method was first developed by Nishizawa et al [13, 16] for glass fibers, and subsequently it was adapted to POFs. The first GI POF was reported in 1982 [43]. Initially, the GI profile was formed by copolymerizing two or three kinds of monomers with...
