Multiple Incoherent Deconvolutions for Improving the Image Resolution of Diffraction‐Limited Imaging Systems

Advanced Photonics Research, EarlyView.
Multiple incoherent nonlinear deconvolutions (MIND) has extended dimension for optimization that provides a better solution than Wiener deconvolution and nonlinear reconstruction. MIND minimizes deconvolution noise by averaging over multiple deconvolutions each with different system aperture that effectively enhances the resolution.

Active Formation of Friedrich–Wintgen Bound States in the Continuum in a Hybrid Plasmonic–Photonic Structure

Advanced Photonics Research, EarlyView.
A method is proposed for actively generating Friedrich–Wintgen bound state in the continuum (FW BIC) in a hybrid plasmonic–photonic structure near the commercially important communication wavelength. In addition, interactions between dark and bright modes can further form the FW BIC and support electromagnetically induced transparency‐like with maximum

Understanding the Temperature Conditions for Controlled Splicing Between Silica and Fluoride Fibers

Advanced Photonics Research, EarlyView.
Thermal splicing conditions are investigated between silica and ZrF4 fibers, focusing on mechanical strength. A fiber Bragg grating characterises the thermal profile in the filament splicer's hot zone. Results indicate a narrow temperature window for strong joints.
