Developing better processes for deposition and coating of thin films. An integrated circuit, in essence, is a series of electrically coimected thin films. Thin films are the key stractural feature of recording media and optical fibers, as well. 

FIGURE 8.4 Configurations for several different kinds of optieal fiber sensing systems are shown. The eommon faetor in all these systems is the use of an optical fiber as an integral element in the system, either to earry light to and from diserete sensors (often referred to as optrodes), or as sensitive elements themselves (intrinsie fiber sensors).

For both types of micro devices, a stainless steel frame was used as holder and Viton gaskets were applied for sealing ]72-74], A clear PMMA cover plate was also used and served for compression. This cover plate provided housing for a mini UV lamp used for irradiation. The detection imit was packaged in a similar fashion. Optical fibers were also integrated. 

Miniaturized chemical analysis systems have been developed for most macroscopic counterparts (Dittrich et al. 2006). The availability of optical fibers, light sources, and detectors in the visible UV and near-infrared (NIR) wavelengths makes it possible to integrate spectroscopic measurements in microreactors (Lobbecke et al. 2005). Fourier transform infrared spectroscopy (FTIR) is an efficient, broadly applicable... 

Now we will assume in addition that the total measured fluorescence is proportional to the above volume average. This can be accomplished experimentally by suspending the fluorescent particle in an integrating enclosure and monitoring the fluorescence with an optical fiber which is pushed through a small hole in the side of the enclosure. Our interest in what follows is to use Eq. (8.4) to simulate a fluorescence excitation spectrum.

In January 1992. E. Desurvire (Columbia University Center for Telecommunications Research) reported that optical fibers made from silica glass and traces of erbium can amplify light signals when they are energized by infrared radiation. Desurvire developed an efficient radiation source (referred (o as a laser diode chip) that, when integrated into a fiber optic communication system, can increase transmission capacity by a factor of 10(1. 

Fluorescence from labeled adsorbed protein has also been excited with the evanescent surface wave created by integrated optics. Both optical fiber I60) and flat rectangular waveguides193) have been used. Interesting use of optical fiber as a remote protein sensor was demonstated the excitation light was sent down the fiber whose tip was immersed in protein solution, evanescently excited fluorescence was collected by the same fiber and delivered to a scanning monochromator 160).
