Coherent diffraction imaging (CDI) enables diffraction-limited high-resolution imaging without using high-quality lenses. It will be desirable to combine it with multiple spectral light sources to achieve chemically resolved imagi

A laser has been demonstrated to achieve tunable mode-locked operation using a multifunctional long-period fiber grating (LPFG). By introducing an LPFG with a relatively high polarization-dependent loss of up to 21 dB into the las

In this Letter, a coding aperture design framework is introduced for data sampling of a CUP-VISAR system in laser inertial confinement fusion (ICF) research. It enhances shock wave velocity fringe reconstruction through feature fu

This study introduced a differential polarization division multiplexing (DPDM) scheme for all-fiber high-accuracy spectral measurement. Launching two orthogonal linearly polarized light beams into multimode fibers, the DPDM elegan

In this paper, we proposed and experimentally demonstrated an 8-channel O-band distributed feedback (DFB) laser array with highly uniform 400 GHz spacing and high output power for optical input/output (I/O) technology. The grating

In this paper, we demonstrate the single-fiber and two-wavelength time transfer (SFTWTT) over a 2061 km field fiber loop-back link network with a synchronous wavelength-division and time-division multiplexing access (WD-TDMA). Thi

Coherent interactions between excitons strongly coupled to plasmons are vital for quantum information devices. For practical applications, suppressing the incoherent dissipation pathways in the hybrid system is essential. Here, we

In this study, we investigate the intensity and spectral fluctuations in surface-enhanced Raman scattering (SERS) signals from individual plasmonic nanocavities. Extremely long-duration blinking components lasting up to minutes ar

The whispering gallery resonator (WGR) represents a promising avenue for the miniaturization of optical devices, while cascaded optical parameter oscillator (OPO) processes have not been realized in the WGR, to the best of our kno

Two-photon polymerization lithography is a technique that provides hundreds of nanometer resolution and full geometric freedom. Several X-ray polymer refractive lenses created by this technique were characterized using differentia
