Recently, many methods based on amplitude or phase modulation to reduce the focal spot and enhance longitudinal field component of a tight-focused radially polarized light beam have been suggested. But they all suffer from size limit 0.36λ/NA large side lobes strength in component. Here, we report method generating tighter focused by focusing azimuthally beams different wavelengths thin photochromic film through high-numerical-aperture lens simultaneously. In this method, suppressing radial...
Abstract High-dimensional quantum key distribution (HD-QKD) is a topic of growing interest in the communication community, not only for its inherent properties but also possible applications. As typical freedom HD-QKD, orbital angular momentum (OAM) has made significant advancements experiments recently. However, airborne scenario, different states suffer amounts misalignment and turbulence. A complete theoretical analysis model transmission characteristics OAM atmospheric channels lacking....
We study the buildup of spatial correlation in a two-dimensional dissipative Rydberg system using time-dependent variational principle. find that sweeping process Rabi frequency and detuning, moderately large decay rate induced by two-photon excitation scheme suppresses significantly long-time scale agreement with experimental results. A relatively dephasing leads to short relaxation time for antiferromagnetic reach stable value. These results provide general view about role various...
Critical parameters of coherent receivers like frequency response, bandwidth, skew, and gain imbalance can be characterized using a polarization-multiplexed laser source. Robust performance is achieved without any active feedback control the launching polarization state into receiver.
This article introduces a four track erase band width (EBW) measurement derived from triple test. The method writes the first center to adaptively control pitch (TP) and final minimize impact system's positioning error during EBW measurement. It uses one-way dual-frequency scan on neighboring magnetic write (MWW) edges further error. Experiment shows that measured decreases with TP decreasing due side reading, cross-track field interaction, edge noise suppression in perpendicular recording....
We theoretically and experimentally study the optical trapping of two different microparticles by a double-tapered fiber probe (DOFP) which is fabricated interfacial etching method. A SiO2 microsphere yeast, or microspheres with diameters, are trapped. calculate measure forces on microparticles, discuss impacts geometrical size refractive index forces. Both theoretical calculation experimental measurements indicate that if particles have same index, larger second particle is, force is....
Abstract The high-dimensional quantum key distribution (HD-QKD) encoded by orbital angular momentum (OAM) presents significant advantages in terms of information capacity. However, perturbations caused free-space atmospheric turbulence introduce random fluctuations OAM transmittance, impacting the performance system. Currently, there exists a gap theoretical analysis concerning statistical OAM-encoded QKD systems. In this study, we analyze security systems combining probability transmission...
