Functionalized polymer waveguide optical switching devices integrated with visible optical amplifiers based on an organic gain material

Visually Monitoring the Compactness of Polymer Matrixes Coded by Disparate Luminescence

“…Meanwhile, three anisotropic polymer materials including poly­(ε-caprolactone) (PCL), poly­(styrene- b -butadiene- b -styrene) (SBS), and poly­(methyl methacrylate) (PMMA) were selected in progressive line with degree of rigidity and regularity in polymer network, to provide distinct microenvironments for VIE molecules. This standpoint of polymer material has been confirmed in previous studies. − Based on this, we strategically doped these polymer materials with DPC compound, respectively, to obtain three uniform polymer films with similar appearance, as in PCL-DPC, SBS-DPC, and PMMA-DPC. Diverse fluorescence emissions were achieved in these films from light orange to blue generated from the different angles of VIE configurations of DPC in three polymer systems.…”

Optical Amplification at 637 and 1067 nm Based on Organic Molecule AQ(PhDPA)2 and NdIII Complex Codoped Polymer Waveguides

“…In recent years, the majority of the previous researches conducted on polymer waveguide amplifiers reported the values of relative gain less than 5.0 and 4.0 dB cm −1 at 0.6 µm and 1.06 µm respectively, as indicated in Figure 11. [1,20,[37][38][39][40][41][42][43][44][45][46][47] Moreover, these polymer waveguide amplifiers all focus on the optical amplification at a single wavelength. Based on AQ(PhDPA) 2 -FDPO (1:4) in this work, the relative gain value of 6.1 dB cm −1 at 637 nm obtained in waveguides with crosssection of 4 × 8 µm 2 is at an advanced level compared with the gains achieved in larger size of waveguides reported so far; in addition, the gain of AQ(PhDPA) 2 -DBFDPO (1:4) of 4.8 dB cm −1 is also a pretty good gain performance at 0.6 µm.…”
