Currently, the loss of chalcogenide fibers is two or more orders magnitude higher than theoretical predictions. A major factor contributing to this difference optical scattering caused by rough interfaces between fiber core and cladding. We fabricate an preform using extrusion-assisted hot-diffusion method. The quality core-cladding interface diffusion was characterized scanning electron microscope (SEM)-energy-dispersive x-ray spectroscopy (EDS) Raman spectroscopy. depth 40.5 μm achieved in...
A simple and compact scheme for the phase-locking of two photonic crystal fibre (PCF) lasers is presented studied experimentally. In experiments, PCF are mutually injected by direct transmission coupling lasers. The interference strips high contrast ratio stability even in power operation. 39W coherent output obtained with combining efficiency 97.2%.
In this paper, a deep learning framework for space-time adaptive processing is developed. Firstly, set of clutter covariance matrixes (CCMs) are modeled based on the prior parameters radar and navigation system with respect to all possible levels non-ideal factors, columns each CCM formulated as undersampled noisy linear measurements sparse coefficients corresponding angle-Doppler spectrum. Then original spectrum coefficients, obtained by least-square estimation from CCMs known steering...
