Polymer/silica hybrid waveguide amplifier at 532  nm based on NaYF₄:Er³⁺, Yb³⁺ nanocrystals

Abstract

An optical waveguide amplifier, which can solve the problem of optical attenuation in optical network transmission, is the key technology to solve optical chip integration and optical interconnection. Here, to the best of our knowledge, we propose a novel polymer/silica hybrid waveguide amplifier at 532 nm for the first time. The research is of great significance to the improvement of short distance communication and visible light communication system. The waveguide amplifier was designed as an embedded structure based on N a Y F 4 : E r 3 + Y b 3 + nanocrystals, which were synthesized by high-temperature thermal decomposition. When the input signal power was 0.1 mW, and the pump power was 300 mW, a relative gain of 4.3 dB was obtained on an 8 mm waveguide. This result is of great research significance to break the distance limit and make all-optical transmission a reality.

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

“…Therefore, it is effective to form embedded waveguides by fabricating grooves in the lower cladding and filling the active materials as cores. [31][32][33] The embedded waveguides can effectively address the problem of difficult etching when using active materials to prepare waveguides; however, there is a problem of optical field leakage in planar waveguides. [33][34][35] This problem can be effectively solved in evanescent-field waveguides.…”

“…Another method is filling polymer materials into silica groove. With mature technology of silica-based PLC foundry, this kind of hybrid devices show great potential for commercial applications [ [30], [38]]. In Fig.…”

“…Benefitting from large TOC, lower heat conductivity and high-power conversion efficiency, polymer-based PLC technology is an ideal platform for thermo-optic switches. Besides, polymer-based PLC is a potential platform for multifunction integration and have been demonstrated in a variety of applications, including optical network units (ONU) [23]- [25], optical phase arrays (OPA) [26], [27], high speed electro-optic (EO) modulators [28], [29] and optical amplifiers [30], [31]. Among the polymer devices, they are mainly based on straight waveguides or Mach-Zehnder interferometers (MZIs) structure.…”
