Semiconductor lasers have a tremendous potential for use in optical communication systems due to their high efficiency, small size, and direct modulation capability. Because of their small size, they become the ideal source for optical radiation to be utilized in an optical fiber transmission system. The reason for developing an optical communications system is that these systems can take advantage of the large bandwidth that optics has to offer. For example, in a conventional copper wire communication system, the bandwidth of the transmission channel, i.e., the coaxial cable, is limited to approximately 300 MHz. In a normal telephone conversation, fi equency components up to 3 kHz are required for the listener to understand the conversation. By multiplexing many telephone conversations on different carrier fi equencies, approximately 100,000 conversations can be sent through a single...

Transmission properties. The recent interest in erbium- (Er +-)doped fiber amplifiers (EDFA) originates from the recognized fact that the optical fiber transmission windows for silica or fluoride glasses (fig. 34) are in tune with the wavelengths of the two Er + transitions I13/2 I15/2 at 1.5 pm, and Ii 1/2 I13/2 at 2.7 pm. 

Concentrating Collectors. Hybrid solar lighting systems use sun-tracking focusing mirrors and optical fiber transmission to provide interior lighting. Typically half of the incident sunlight can be transmitted to rooms, where it replaces or supplements conventional lighting. 

The bandwidth of a fiber determines the maximum transmission data rate or maximum transmission distance. Most common POF (plastic optical fiber) transmission systems adopt on-off keying by direct modulation of the optical source (laser or light-emitting diode). If an input pulse waveform can be detected without distortion at the other end of the fiber, the maximum link length is limited by the fiber attenuation. However, in addition to the optical power attenuation, the output pulse is generally broader in time than the input pulse. This pulse broadening limits the transmission capacity, namely, the bandwidth of the fiber. The bandwidth is determined by the impulse response as follows [1] Optical fibers are usually considered quasi-linear systems thus, the output pulse is described by... 

Various types of signal impairment that are inherent in optical fiber transmission systems degrade the link performance. Any signal impairment in an optical link reduces the optical power transmitted to the receiver compared to the ideal case. This lower power reduces the SNR of the link compared to the case with no impairment [11]. Because a reduced SNR leads to a higher BER, additional signal power is required at the receiver to maintain the same BER as... 

For 3D-waveguides and integrated optical components, usually the insertion loss has to be measured according to Federal Standard 1037C (raD-STD-1037C, 2000), it is defined as the loss resulting from the insertion of a device in an optical fiber transmission...
