The sensor probes the sensitive phase response at plasmonic resonance using stable spectral color profile. In the optical design, the plasmonic sensor surface is placed inside a polarizer pair with perpendicular polarization orientation. The polarizer pair originally does not allow excitation light to pass through. At plasmonic resonance, the differential phase response between p- and s-polarization light rotates the polarization ellipse, which allows the excitation light to leave the polarizer cavity. Furthermore, the differential phase response is wavelength dependent and a phase-spectral color profile is created at the SPR image. The spectral-phase color profile is not sensitive to environmental vibration comparing to conventional interferometric phase SPR detections.

We also provide a distance formula that determines the position at which the FFFPLGB begins to acquire its perfect property. This distance formula can improve the practical implementation and operation of the FFPLGB. Quantitative research findings show that the FFPLGB, owing to its unique multi-ring structure, possesses more superior perfect property compared to classical perfect vortex beam. Compared to the declining received probability of Laguerre-Gaussian beam (LGB) with increasing OAM mode, FFPLGB demonstrates the ability to maintain similar OAM spectrum distributions across different OAM modes. Furthermore, the OAM spectrum distribution of FFPLGB remains largely invariant to changes in radial orders, highlighting its robustness and superior performance in optical applications.

This paper employs the LP-mode diversity method to investigate the amplification characteristics of vector modes in FM-EDFAs, and compares it with the intensity model. It is demonstrated that the two methods may give the same calculation results only for the case of circularly symmetric mode pumping, that is, the computation based on the intensity model is no longer valid in the case of non-circularly symmetric mode pumping. Based on the LP-mode diversity method, we discuss the evolution of the transverse intensity distribution of vector modes in FM-EDFA, the mode combination types of DP signals, and the approaches to reducing PDG.

Future optical transmission should adapt its bit rate and reach according to network demands by employing multidimensional modulation formats while maintaining low costs and complexity for practical implementation. In this paper, we utilize a phase-conjugated twin waves (PCTWs) technique to eliminate nonlinear phase noise (NLPN) in optical transmission systems that employ multidimensional modulation formats. Four-dimensional (4D) modulation formats, namely, Ball, Cluster, polarization-switched (PS)-quadrature phase shift keying (QPSK), and 32 set partitioning (32SP)-16 quadrature amplitude modulation (16QAM), are employed to modulate signals transmitted over long-haul fiber links. In the proposed system, the twin signals are spatially propagated over two similar optical links at a rate symbol rate of 20 Gsymbol/s. At the receiver, the PCTWs are recovered and then coherently combined for mitigating the effects of NLPN and improving a signal-to-noise ratio (SNR). The results indicate that the PCTWs technique enhances system performance for all four 4D modulation formats. Specifically, the achievable reaches is extended by 55 % for PS-QPSK, 48 % for 32SP-16QAM, 18 % for Custer, and 27 % for 8-Ball at a bit error rate (BER) of 10<sup>−3</sup>.
