Anisotropic Second‐ and Third‐Harmonic Hermite–Gaussian Beam Generation with NbOI2 Holograms

open access: yesAdvanced Photonics Research, EarlyView.
Anisotropic second‐ and third‐harmonic Hermite–Gaussian (HG) beam generation is demonstrated with ultrathin NbOI2 grating holograms to produce the nonlinear HG01 and HG10 modes with high anisotropy ratios. The relative magnitudes of the second‐ and third‐order nonlinear susceptibility tensor elements of NbOI2 crystal are extracted. These demonstrations

Synthesis of Self‐Healing Microbeam by Superposition of Self‐Decelerating Corner‐Diffraction Beams

open access: yesAdvanced Photonics Research, EarlyView.
Quasi‐nondiffracting (QND) beams boast long‐range propagation and self‐healing capabilities but require complex beam‐forming platforms. In contrast, the photonic nanojets (PNJs) boast simple platforms but are utilized primarily for near‐field applications. This work aims to hybridize the QND and PNJ beam concepts with a view to realize microscale, self‐

Monolithically Integrated Fourier Injected REsonator (FIRE) for Passive Coherent Laser Combination

open access: yesAdvanced Photonics Research, EarlyView.
Semiconductor diode‐based Fourier Injected REsonator (FIRE). The concept of free space FIRE, formerly known as the self‐Fourier cavity, is demonstrated for the first time on a chip‐scale device. A very high laser array coherence (97.7% fringe visibility), corresponding to single out‐of‐phase supermode operation, is reported.
