With the rapid development of silicon photonic chips and integrated photonic circuits, erbium-doped optical waveguide amplifiers have been received more and more attention in order to compensate for the transmission and coupling losses caused by the integration of optical devices on a chip. Pumping wavelength and pumping efficiency directly affect the gain and noise figure of the amplifier. In this paper, we propose an innovative dual-wavelength pumping method based on an erbium-ytterbium co-doped optical waveguide amplifier with simultaneous pumping at 980 nm and 1480 nm. A relaxation method based on the fourth-order Range-Kutta method is used to solve the rate and propagation equations and simulate the gain characteristics of the dual-wavelength pumping method are simulated for different ytterbium-erbium ion concentration ratios, erbium ion concentrations and ratio K between the 980 nm and total pump power. From the simulation results, it can be seen that the gain of the dual-wavelength pumping method is higher than that of the single-wavelength pumping methods when the erbium ion concentration exceeds 3×1026 /m3. At higher erbium ion concentrations, the dual-wavelength pumping method can provide higher gain for optical waveguide amplifiers, and may be able to become a new choice of pumping method for optical waveguide amplifiers.

Relying on a reverse energy transfer mechanism between erbium (Er3+) and ytterbium (Yb3+) ions, optical gains at wavelengths of 1550, 980, and 1067 nm are achieved in NaYF4: Er3+, and Yb3+ nanoparticles‐doped polymer waveguides under excitation of low‐power light‐emitting diodes (LEDs) instead of 976 or 1480 nm semiconductor laser as pump sources. The optical gains at 1550, 980, and 1067 nm are demonstrated in five waveguide structures: active‐rectangular, evanescent‐field with and without an aluminium (Al) reflector, and dual‐active hybrid with and without an Al reflector. The maximum relative optical gains of 6.6, 4.0, and 3.8 dBcm−1 are realized at 1550, 1067, and 980 nm, respectively, in a 5 mm long dual‐active hybrid waveguide with cross‐section of 4 × 10 µm, and a ≈100 nm‐thick Al reflector grown under the lower cladding layer under excitation of a 395 nm LED. This work proves the feasibility of using a low‐cost LED to realize multi‐wavelength amplification in a dense wavelength‐division multiplexing system and is thus valuable for the development of complex multi‐functional photonic‐integrated‐module mixed‐band optical communication systems.

High‐efficiency optical waveguide amplifiers are becoming desperately desirable in integrated photonics to provide sufficient power compensations. Various material platforms have been employed to realize on‐chip waveguide amplifiers to date. Chalcogenide glasses (ChGs), as one of the well‐developed and promising optical platforms, have been extensively studied due to the excellent properties of low loss and high third‐order nonlinearity. However, the performances of their waveguide amplifiers are far from expectations on account of the intrinsic natures of low rare‐earth ion solubility, low luminous efficiency in chalcogenide hosts as well as the high photoinduced absorption loss in certain compounds. Here, a heterogeneous optical amplifier is proposed and demonstrated in an alternative Ge25Sb10S65 (GeSbS) waveguide via integration with an erbium‐doped aluminum oxide (Al2O3) layer for the first time. A total 4.6 cm long spiral waveguide exhibits an internal net gain as high as 6.27 ± 0.618 dB at 1533 nm and a broad gain bandwidth over 40 nm ‐ ranging from 1520 nm to 1560 nm upon 1480 nm pumping. It is believed that this heterogeneous configuration will greatly enrich the functionality and versatility of the ChGs integrated photonics.
