A Review on 3D Integrated Approaches in Multimode Optical Polymeric Waveguide Fabrication

Thermochromic photoluminescent 3D printed polymeric devices based on copper-iodide clusters

“…In the last 30 years, many fabrication processes have been developed to shape those materials, such as lithography [5], controlled deposition [13] and electrospinning [14]. Generally, PWGs are fabricated employing conjugated polymers, that emit thanks to the long-range π-electron conjugation [15].…”

“…Characterization: 1 H, 13 C and 31 P NMR spectra were recorded on a JEOL ECZR600 FT-NMR spectrometer ( 1 H operating frequency 600 MHz) at 313 K and 298 K for 1 and 2, respectively.…”

“…1 H and 13 C chemical shifts are reported relative to TMS (δ = 0) and referenced against solvent residual peaks. Toluene-d8 deuterated was used as deuterated solvent for 1, while for 2 chloroform-d was employed.…”

The effect of surface modification on adhesion of polymer waveguide on flexible substrate

“…The need for optical interconnection and state of the art of polymeric optical waveguide technology has been previously reviewed by the authors [1]. Concerted efforts in polymer waveguide development have been demonstrated since mid-1990s, which have been reported in numerous applications such as integrated electricaloptical circuit board (EOCB) [2], optical backplanes [3], vertical cavity surface emitting laser (VCSEL) [4] and system-on-package (SOP) [5].…”
