  • Gain enhancement of polymer waveguide amplifier based on NaYF
    In this study, polymer waveguide amplifiers based on NaYF 4: Er 3 +, Yb 3 + nanocrystals were proposed and investigated The gains of polymer optical waveguide amplifiers with backward and forward pump schemes were compared via simulation and experiment The devices were designed with a rectangular waveguide structure
  • Channel polymer optical waveguides embedded in glass: Design . . .
    Developments in polymeric optical waveguides have experienced a large growth over the last years due to their handling simplicity and low cost production [1], [2], [3] Currently, channel optical waveguides are being fabricated with different polymers [4], [5], [6] On the other hand, the scientific collaboration between the Integrated Optics and Immunoelectroanalysis laboratories, at University
  • Terahertz filters based on subwavelength polymer waveguide
    The proposed subwavelength polymer waveguide can be fabricated using the cutting-edge 3D printing technique In addition, as of the proposed filter is based on a cylinder waveguide, the filter feature cancels the polarization dependency of the transmission spectrum of the grating This feature makes these filters more flexible in practice
  • High-efficiency broadband out-of-plane fiber-to-polymer waveguide . . .
    Polymer photonics is receiving significant attention due to its potential for a wide range of integrated photonic applications and wide wavelength transparency Wafer-scale testing is challenging due to low-index contrast in polymer waveguides In this Letter, we demonstrate an amorphous silicon based out-of-plane polymer waveguide grating coupler Simulations predict a maximum efficiency of
  • Directly inscribed multimode polymer waveguide and 3D device for high . . .
    A 75-cm-long circular-core polymer waveguide compatible with standard 50-μm-core multimode fibers (MMFs) is designed and fabricated by using a direct inscribing method for high-speed and high-density optical interconnects The fabricated waveguide has low loss (<0 044 dB cm at 850 nm) and low crosstalk (<−34 dB with a core pitch of 62 5 #x003BC;m) with a negligible coupling loss with the MMFs
  • Polymer optical waveguide recoverable evanescent field . . . - Springer
    Nitroaromatics are a significant concern due to their high explosiveness and potential for water pollution Optical waveguide sensing technology has been employed in the detection of nitroaromatics, leveraging its advantages of affordability, high sensitivity, reusability, and effective detection results However, most current optical waveguide sensors operate on the principle of cumulative
  • Fabrication and characterization of electro-optic polymer silicon . . .
    However, in a silicon-polymer hybrid structure, light is strongly confined in the high-index silicon core, which is a drawback when light–matter interaction in the low-index polymer cladding is desired Slot waveguides [2] are typical nanostructures that can guide and confine light within a nanoscale low-index material surrounded by higher
  • Flexible Multimode Polymer Waveguide Arrays for Versatile High-Speed . . .
    Multimode polymer waveguides in particular allow the formation of high-capacity optical backplanes and cost-effective board-level optical interconnects Their formation on flexible substrates offers significant practical advantages and enables their deployment in environments where shape and weight conformity become particularly important, such
