Dual-functional polymeric waveguide with optical amplification and electro-optic modulation
TL;DR: In this paper, the dual functions were achieved by doping neodymium chloride hexahydrate and chlorophenol red, and the optimized doping concentration of Nd+3 is 6.7×1019 cm−3.

Dual-functional polymeric waveguide with optical amplification and electro-optic modulation
TL;DR: In this paper, the dual functions were achieved by doping neodymium chloride hexahydrate (NdCl 3 -6H 2 O) and chlorophenol red (C 19 H 12 Cl 2 O 5 S).

Electroptic Polymer Linear Modulators Based on Multiple-Domain Y-Fed Directional Coupler
TL;DR: In this paper, the authors developed an analytical method to optimize the design of Y-fed direction couplers at large modulation depth from 10% to 50 dB, which can potentially achieve 120 dB spurious free dynamic range.
