In this paper, we propose a structure that realizes the plasmon induced transparency (PIT) effect through metal-insulator-metal waveguide and T-shaped resonator. PIT is a quantum interference effect, which can lead to a sharp transparency window in the wide absorption spectrum. By changing the coupling strength between the light and dark states of PIT effect, the distribution of electromagnetic field around the quantum-dot nanowire can be affected. Theoretical analysis showed the Purcell effect caused by the T-shaped resonator increases the emission rate of quantum dots by nearly 900 times. This ultrafast single-photon source has great potential in quantum communication and optical interconnection.

Routing and wavelength assignment algorithms for Low Earth Orbit (LEO) satellite communication are studied in this paper. Based on intersatellite hops and wavelength utilization, the calculation model of path weight is established. In order to achieve the optimal allocation of routing and wavelength resources in Software Defined Network (SDN) network architecture, path selection and wavelength allocation are completed from the perspective of path weight. Finally, the proposed algorithm is compared with the existing algorithms. The simulation results show that the proposed algorithm can reduce the blocking rate and improve the wavelength utilization.

We introduce a transmission scheme using Fast-than-Nyquist rate in multi-band optical transmission system. A method of non-orthogonal transmission through doubinary filter is proposed and applied in multi-band optical transmission system. The simulation results show that FTN transmission can enhance the spectral efficiency of system, and we can restore signal through force zero equalization technology.

In this paper, a cost-effective and high-precision optical fiber sensing system based on VT-DBR laser for white light interferometry is proposed. A low-noise, low power, high modulation-bandwidth laser driver with excellent long-term stability is described. A stable and high laser drive current has been obtained using a high-precision ADN8810 chip. Self-designed data acquisition module based on the Analog-to-Digital acquisition chip AD9226 was developed to collect data from Fabry-Perot (FP) sensor interference spectrum, and then the acquired spectral data were transferred to the PC by USB serial port. Laser scanning monitoring, data acquisition and data transmission are carried out using a field-programmable gate array (FPGA). An integral temperature chip ADN8831 was used to drive the thermoelectric cooler controller of the Vernier Tuned Distributed Bragg Reflector (VT-DBR) tunable laser. This system has a broad sweep range (1527-1567nm)with a wavelength interval of 8 pm, and a full-spectrum scanning rate of 100 Hz. Contrast observation of spectrum experiment with commercial optical sensing interrogator sm125 and temperature sensing experiments of FP sensor cavity length demodulation using cross-correlation algorithm was carried out to investigate the performance of the system. Experimental results show that the system is reliable and has superior performance. Benefiting from the self-developed and integrated essential electrical circuits, the whole system has small size, cost-effective and potential application value.

A functionalized tilted fiber grating (TFBG) sensor based on polyaniline (PANI) was proposed for the detection of environmental pH. The pH sensor is fabricated by coating PANI to the surface of optical fiber. The transmission spectrum of the sensor changes significantly with the change of external pH value. Moreover, the sensitivity is directly related to the thickness of the polyaniline film. The test results show that the pH detection range is 2-11.2, and the maximum sensitivity is up to 1.82 dB/pH. Furthermore, the proposed pH sensor exhibits good biochemical compatibility, which exhibits great application prospects in biomedicine field.
