Example text

Ray Dingle and Charles Henry [1] applied for a patent on quantum well (QW) lasers in 1976. Here, they listed the benefits of reducing the dimensionality of the active area of a semiconductor laser when changing from a three-dimensional double heterostructure (threedimensional structure) to a QW (two-dimensional structure) and finally to a quantum wire structure (1D structure). 1. Both the energy eigenvalues and the density of states become a function of the lateral dimension in x-, y-, and z-direction.

The key technologies are related to fiber selection and arrangement, to amplifier design, to modulation formats, to detection techniques, and to advanced impairment-mitigation solutions. 1. 15 Chapter 15. Future optical networks (Michael O’Mahony) In the past few years Internet traffic, doubling annually, has dominated the network capacity demand, which has been met by the advances in lightwave communications. The transformation from a circuit-switched, voice-centric to a packet-switched, IP-centric network is well underway; amplified WDM transmission systems with terabits-per-second capacity are being deployed; rapid reconfigurable networking and automatic service provisioning are being implemented.

4 ps. BER measurements were performed by varying the optical input power at the preamplifier and for two different drive currents. Error-free modulation (BER < 10–10) was achieved for 120 mA drive current, only limited by measurement time. For lower drive current, a power penalty of 2 dB and an error floor at BER < 10–9 were found. 2. 14 BER measurement of QD amplifier module at 40 Gb/s for different drive currents; the inset shows the eye pattern for 120 mA drive current (this figure may be seen in color on the included CD-ROM).
