“…Thus, while (59) remains a limit, in general there may be no way to approach it. One may try to replace R(d) of (61) by some realistic R(d) obtained with whatever one can do to U , but contrary to what is stated in ref [56], it is not clear how such R(d) may be evaluated. On the other hand, from experience the R(d) for a Gaussian parameter with different encoding criteria vary litle, and so the exact form of R(d) is not expected to make any major difference in the final result (59).…”

“…Note that (56) goes to zero as D → ∞. This is because infinite capacity is obtained when the narrowband expression is extrapolated to infinite bandwidth, which is not physically meaningful as the hf dependence becomes important [21,37].…”

“…For example, the use of PSA not only improves the SNR by a factor of 2 for coherent state sources in a long amplifier chain, it also significantly reduces the Gordon-Haus soliton timing error [55]. Considerable experimental progress [56] has been made on such possible application, but the required phase coherence renders it impractical. For on-off signals, the use of PNA leads to the following error probability…”

The principles are elaborated which underlie the applications of general nonclassical states to communication and measurement systems. Relevant classical communication concepts are reviewed. Communication and measurement processes are compared. The possible advantages of nonclassical states in classical information transfer are assessed. The significance of novel quantum amplifiers and duplicators in communication is emphasized. A general approach is developed for determining the ultimate accuracy limit in quantum measurement systems. It is found that bandwidth or mode number is a most important parameter and ultrahigh precision measurement is possible in systems with a fixed energy but many modes. The problem of the standard quantum limit in monitoring the position of a free mass is also addressed.

“…As a result, dense wavelength division multiplexing (DWDM) systems and optical packet switching (OPS) systems that provide high capacity and flexibility over the entire network have become a key option in the next generation networks. Optical buffer [1][2][3][4][5][6] is one of the most important components in OPS networks as it can solve the contention of the data packets in the optical domain without O/E/O conversion. Practical buffers are implemented based on slow-light effect [4,5] , fiber delay lines (FDL) [6] , or fiber loop [7][8][9][10][11][12][13][14] .…”

The data packet buffering can be implemented in dual loop optical buffer (DLOB) through cross-phase modulation (XPM) between the control signal and the data packets. However, the output equality of dual wavelength signals will degrade due to the unbalanced gain and phase shift. This problem can be resolved by power equalization using the saturation characteristics of SOA. The data packets with 2.5 Gb/s can be buffered in DLOB for 16 cycles corresponding to 16.5 s.The extinction ratio of the output packet is 8 dB while the S/N is 8.1 dB.As the traffic of information and multi-services increases, broadband and high capacity transmission networks have attracted extensive research interests. As a result, dense wavelength division multiplexing (DWDM) systems and optical packet switching (OPS) systems that provide high capacity and flexibility over the entire network have become a key option in the next generation networks. Optical buffer [1][2][3][4][5][6] is one of the most important components in OPS networks as it can solve the contention of the data packets in the optical domain without O/E/O conversion. Practical buffers are implemented based on slow-light effect [4,5] , fiber delay lines (FDL) [6] , or fiber loop [7][8][9][10][11][12][13][14] . To the best of our knowledge, all of the above configurations are only suitable for single wavelength signal buffering. With the development of the wavelength division multiplexing (WDM) technology, multi-wavelength buffers are imminently needed. In this paper, dualwavelength signal buffering in DLOB based on a collinear 3 3 fiber coupler is presented and experimentally demonstrated [9][10][11] . By introducing an SOA after the DWDM and utilizing the gain saturation characteristics of SOA, the uniform output bits power could be obtained, and the distortions of output pulses can be successfully mitigated and the buffer performance is greatly improved.The experimental setup for dual-wavelength signal buffering is shown in Fig.
