NONLINEAR OPTICAL PROPERTIES OF FIBERS A selection of these are included in "Further Reading" at the end of this topic. We will content ourselves with an overview of the subject, and consider nonlinear effects which are most important in either limiting or enhancing the performance of fibers. To date, most of the applications of nonlinear […]
INTRODUCTION Basic elements of an optical fiber communication system include the transmitter [laser or light-emitting diode (LED)], fiber (multimode, single-mode, or dispersion-shifted), and the receiver [positive-intrinsic-negative (PIN) diode and avalanche photodetector (APD) detectors, coherent detectors, optical preamplifiers, receiver electronics]. Receiver sensitivities of digital systems are compared on the basis of the number of photons per […]
