Theoretical calculations of exciton in InAs/InP self-assembled quantum wires are presented in this paper. The Coulomb interaction between the electron and hole is calculated by using a fast Fourier transformation. In our simulations, strain effects are taken into consideration. Finally, we obtain the exciton binding energy in quantum wires by solving 1D Schrodinger equation along the quantum wire direction.

We propose a novel suboptimal design algorithm for PON outside plant deployment. Under realistic restrictions such as possible fiber paths, splitting ratio of optical splitters, and locations of the central office and subscribers are given, the algorithm can automatically generate the suboptimal PON network in terms of total fiber length.

A novel quantum dots(QDs) optical fiber amplifier was proposed and demonstrated. It was fabricated by dip-coating the PbSe quantum dots doped sol onto the taper region of fiber coupler. The PbSe quantum dots was synthesized according to a colloidal method. And a lower refractive index sol was also synthesized as the host of PbSe QDs. A standard single mode fiber was used to make the fusion tapered fiber coupler which had double input and output ports. With the simple structure, a signal and a pump can be injected into the amplifier and excite the PbSe QDs through evanescent wave. As shown in the experimental results, the amplified light wave was observed at 1550nm wavelength with 980nm wavelength LD as pump.

The fluorescence intensity ratio (FIR) technique for optical fiber-based temperature sensing is discussed in many previous papers. But in the high temperature sensing the FIR technique has been researched a little. In this paper, the temperature dependence of fluorescence in erbium-doped fiber between ∼700 and ∼1300°C is discussed and experimentally demonstrated. 1450nm and 1530nm wavelengths are chosen to calculate the FIR, and the temperature coefficient could achieve ∼ 0.003dB/°C.

We propose an improved postponed lightpath teardown (PLT) strategy by introducing a lightpath splitting mechanism in multi-layer optical networks. Based on the original PLT strategies, this paper introduces a mechanism to split the unoccupied shortest lightpaths into shorter ones when the network operates in a steady state. Results show that the improved strategy achieves higher utilizations of both wavelength-links and transceivers under different scenarios of load and transceiver number, and significantly reduce the blocking probability (CBP).

Zero Touch photonic solutions require a carefully designed control plane to cope with physical impairments and the need for 3R regeneration. GMPLS providing the flexibility to add regeneration where needed, extends the reach of WDM network domains beyond the physical limits of pure wavelength switching.

We have theoretically studied pulse propagation in a normal-dispersion optical cubicon fiber amplifier (NDOCFA) with an arbitrary longitudinal gain proflie, and have obtained an analytic solution for the nonlinear Schrödinger equation that describles such an amplifier. The results show that the characteristics of self-similarity and linear chirp will be lost due to third-order dispersion. However, by using a dispersion compensation technique, one can obtain efficient and high-quality compressed pulses. The numerical simulation is consistent with the analytic results.
