TL;DR: In this article, a pseudo-high-order GVLVS with a two-humped pulse along one polarization and a single-hump pulse along the orthogonal polarization was obtained.
Journal ArticleDOI
Performance comparison of different modulation formats over free-space optical (FSO) turbulence links with space diversity reception technique
TL;DR: The purpose of this paper is to study and compare the bit-error-rate (BER) performance of several widely used modulation formats under different atmospheric turbulence scenarios with and without SDRT, and derives a series-form formula for evaluating the BER performance of the DPSK format in the Gamma-Gamma distributed channel with SDRt.
Journal ArticleDOI
Cascaded fiber-optic Fabry-Perot interferometers with Vernier effect for highly sensitive measurement of axial strain and magnetic field
TL;DR: A highly sensitive fiber-optic sensor based on two cascaded intrinsic fiber Fabry-Perot interferometers (IFFPIs) is reported and it is found that the strain sensitivity of the proposed sensor can be improved from 1.6 pm/με for a single IFFPI sensor to 47.14 pm/ με by employing the Vernier effect.
Journal ArticleDOI
Ultrawideband monocycle generation using cross-phase modulation in a semiconductor optical amplifier
TL;DR: A novel scheme to generate ultrawideband (UWB) monocycle pulses based on cross-phase modulation of a semiconductor optical amplifier (SOA) and an optical bandpass filter (OBF).
Journal ArticleDOI
High-energy laser pulse with a submegahertz repetition rate from a passively mode-locked fiber laser
TL;DR: Without any discrete dispersion-compensation components or conventional spectral filters, the SESAM works together with the strongly chirped pulse and the nonlinearity induced spectrum broadening to perform a filtering-equivalent function, thus stabilizing the mode locking.
