Abstract Two-dimensional (2D) materials have received extensive attention in
optoelectronics because of their unique characteristics. However, due to the extremely thin …

We demonstrate 5 dB net gain in an erbium-doped tellurium-oxide-coated silicon nitride
waveguide. The amplifier design leverages the high refractive index and high gain in erbium …

Supercontinuum generation (SCG) is an important nonlinear optical process enabling
broadband light sources for many applications, for which silicon nitride (Si_3N_4) has …

We report on thulium-doped waveguide amplifiers integrated on a low-loss silicon nitride
platform. The amplifier structure consists of a thulium-doped tellurium oxide thin film coated …

An alternative method for characterizing optical propagation in waveguide structures based
