Photonic Metrology with Hierarchic Quantum Frequentist Bounds

open access: yesAdvanced Photonics Research, EarlyView.
This paper proposes photonic metrology with hierarchical quantum frequentist bounds. The present model tightens the Quantum Cramér‐Rao Bound using a hybrid classical‐quantum framework. The experiment validates the hierarchical frequentist bounds for single‐qubit phase estimation.

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.
