Manipulating mode degeneracy for tunable spectral characteristics in multi-microcavity photonic molecules

期刊: OPTICS EXPRESS, 2021; 29 (7)

Optical microcavities are capable of confining light to a small volume, which could dramatically enhance the light-matter interactions and hence impro......

Twin curvilinear vortex beams

期刊: OPTICS EXPRESS, 2021; 29 (9)

We report on a novel curvilinear optical vortex beam named twin curvilinear vortex beams (TCVBs) with intensity and phase distribution along a pair of......

Temporal mode properties of Raman scattering in optical fibers

期刊: OPTICS EXPRESS, 2021; 29 (9)

By investigating the intensity correlation function, we study the temporal mode properties of spontaneous Raman photons generated in single mode fiber......

3D reconstruction of the specular surface using an iterative stereoscopic deflectometry method

期刊: OPTICS EXPRESS, 2021; 29 (9)

Phase measuring deflectometry (PMD) is an effective technique for three-dimensional measurement of specular surfaces. However, the ambiguity of monosc......

Profile-based intensity and frequency corrections for single-snapshot spatial frequency domain imaging

期刊: OPTICS EXPRESS, 2021; 29 (9)

We have proposed the profile-based intensity and frequency corrections for single-snapshot spatial frequency domain (SFD) imaging to mitigate surface ......

Anomalous contrast in broadband THz near-field imaging of gold microstructures

期刊: OPTICS EXPRESS, 2021; 29 (10)

THz scattering-type scanning near-field microscopy (s-SNOM) has become a powerful technique for measuring carrier dynamics in nanoscale materials and ......

Magneto-optically reorientation-induced image reconstruction in bulk nematic liquid crystals

期刊: OPTICS EXPRESS, 2021; 29 (11)

We theoretically propose the magneto-optically reorientation-induced image reconstruction in bulk nematic liquid crystals (NLCs). The underlying signa......

Femtosecond laser patterned superhydrophobic/hydrophobic SERS sensors for rapid positioning ultratrace detection

期刊: OPTICS EXPRESS, 2021; 29 (11)
