“…To increase the absorption cross section, ytterbium ions (Yb 3+ ) are usually codoped as a sensitizer. Er 3+ -Yb 3+ codoped waveguide amplifiers (EYCDWAs) are therefore expected to be an attractive high-gain medium material for optical amplification15161718. With the development of optical communication, optical waveguide amplifiers with high gain are required urgently.…”

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.

This paper reviews the recent developments in rareearth-ion-doped planar and channel waveguide lasers. Optical gain in rare-earth-ion-doped waveguides has been increased by two orders of magnitude to ~1000 dB/cm and waveguide lasers with extremely high slope efficiencies and output powers exceeding the Watt level have been demonstrated. Of particular interest in integrated optics is the recent integration of rareearth-ion-doped channel waveguide lasers in amorphous materials directly deposited on a silicon substrate. Remarkable performance with respect to slope efficiency, output power, and laser linewidth has been achieved.

“…The great success of erbium-doped fiber amplifiers near 1.5 µm has triggered significant research on host materials and fabrication techniques for erbium-doped waveguide amplifiers (EDWA) [1][2][3][4][5]. Optical losses have limited the widespread application of integrated-optical circuit chips.…”

Abstract:We report on the optical-gain properties of channel waveguides patterned into lattice-matched KGd x Lu y Er 1-x-y (WO 4 ) 2 layers grown onto undoped KY(WO 4 ) 2 substrates by liquid phase epitaxy. A systematic investigation of gain is performed for five different Er 3+ concentrations in the range of 0.75 to 10at.% and different pump powers and signal wavelengths. In pump-probe-beam experiments, relative internal gain, i.e., signal enhancement minus absorption loss of light propagating in the channel waveguide, is experimentally demonstrated, with a maximum value of 12 ± 5 dB/cm for signals at the peakemission wavelength of 1534.7 nm.
