Multi-format and linewidth-tolerant carrier phase estimation (CPE) is a vital part of digital signal processing (DSP) units for future elastic optical transmissions to relax the laser linewidth limitation. In this paper, an innovative CPE scheme outp

We propose a novel C-OTDR scheme which not only achieves large dynamic range but also solves the problem of polarization dependence. Simulation and experimental results demonstrate its feasibility and potentiality in ultra-long fiber link monitoring.

A flexural support technique for lightweighted Primary Mirror Assembly (PMA) of a space telescope is presented in this article. The proposed three-point flexural mount based on a cartwheel flexure can maintain the surface figure of the PMA in a horiz

We demonstrate a novel and compact fiber-probe pressure sensor based on a micro-Fabry–Perot interferometer (FPI). The device is fabricated by splicing both ends of a short-section simplified hollow-core photonic crystal fiber (SHC-PCF) with single-

In this letter, we reported long period fiber gratings (LPFGs) fabricated by femtosecond laser pulses direct writing in grapefruit microstructured fiber. The mode field distribution and dispersion property of this fiber was analyzed by finite-element

We experimentally demonstrate a channel-reuse, bidirectional, 10 Gb/s/ λ , long-reach dense wavelength-division-multiplexing passive optical network (DWDM-PON) and an optical beat noise-based automatic wavelength control method for a tunable laser u

We propose and experimentally demonstrate a 40-Gbps virtual single sideband (VSSB) Nyquist-subcarrier-modulation (Nyquist-SCM) direct detection scheme with symbol pre-distortion to mitigate the nonlinear inter-symbol interference (ISI) caused by disp

Neugebauer printing color model can be divided into tristimulus model and spectral model in form. After color subarea, if these two models are directly applied to multicolor separation, the accuracy of color separation is far from enough. A relativel
