Waveguide amplifiers have always been significant key components for optical communication. Unfortunately, the low concentration of rare earth ions doped in the host material and the inadequate optimization of the waveguide structure have been the common bottleneck limitations. Here, a novel material, NaYF4/NaLuF4: 20% Yb3+, 2% Er3+ nanoparticle-Polymeric Methyl Methacrylate covalent-linking nanocomposite, was synthesized. The concentrations of Er3+ and Yb3+ doping increased an order of magnitude. Under a 980 nm laser excitation, highly efficient emission at 1.53 μm was obtained. The characteristic parameters of the single mode waveguide were carefully designed and optimized by using a finite difference method. A formulized iteration method is presented for solving the rate equations and the propagation equations of the EYCDWA, and both the steady state behavior and the gain were numerically simulated. The optimal Er3+ and Yb3+ concentrations are 2.8 × 1026 m−3 and 2.8 × 1027 m−3, and the optimal waveguide length is 1.3 cm. Both theoretical and experimental results indicated that, for an input signal power of 0.1 mW and a pump power of 400 mW, a net gain of 15.1 dB at 1530 nm is demonstrated. This result is the highest gain ever reported in polymer-based waveguide amplifiers doped with inorganic Er3+-Yb3+ codoped nanocrystals.

In recent years, significant progress has been made in the on-chip integration of Ti:sapphire amplifiers and lasers, showing great potential in device miniaturization, cost reduction, and mass production. However, the further integration of such devices on standard CMOS platforms has been challenging due to its limits on the wafer bonding method between gain materials and substrates. Here, we present a novel, to the best of our knowledge, Si3N4 on-chip broadband optical waveguide amplifier scheme with an ultra-wide bandwidth of 650–900 nm and a peak gain of 28 dB based on an ion-sliced Ti:sapphire platform. The difficulty of heterogeneous integration is significantly reduced by growing Si3N4 thin films on Ti:sapphire. Moreover, by using homogeneous bonding combined with ion slicing technology, the target thickness of Ti:sapphire is expected to be easily controlled to less than 1 µm, greatly reducing the device volume and improving its practicality. Through subsequent experimental optimization, this work is expected to provide a new approach for the optimized design and experimental realization of on-chip Ti:sapphire waveguide amplifiers and lasers.
