Advanced Single-Mode Fiber Designs for Lightwave Systems Applicationsng deployed with low losses and near-zero dispersion for lightwave systems applications at wavelengths near 1.3 μn. However, systems of the next generation will undoubtedly include 1.55-μm wavelength applications because intrinsic scattering losses in fused silica glasses are minimized there.

Polarization-Maintaining Optical Fibersates, these are the HE. mode, which has its principal electric field component in the . direction, and the HE. mode, which has principally the . component of the electric field. We hereafter omit the suffix 11 for simplicity and call these modes the HE. and HE. modes.

Modulation Properties of Semiconductor Laserscy of semiconductor lasers can be conveniently modulated by modulating the current to the lasers. These lasers can be modulated at extraordinarily high frequencies because stimulated emission considerably shortens the carrier lifetime below the level of other nonlasing devices such as FETs, photodiodes, and light-emitting diodes.

Semiconductor Laser Transmittersse or frequency information imparted to the optical carrier frequency itself is not used at the receiver. Important increases in receiver sensitivity and selectivity can be derived using intentional optical phase or frequency modulation. Such “coherent” transmission is dealt with in Chapter 25.
