For the first time [to our best knowledge] a high-index-contrast -cut photonic wire waveguide laser, optically pumped at 980 nm wavelength, is designed for continuous-wave operation. Waveguide modes and laser characteristics are numerically computed using a developed full vectorial finite-element method based tool. In order to maximize the output power of the laser, the active cavity length and output mirror’s reflectivity have been optimized, considering different pump power and waveguide background losses. Efficient laser emission is theoretically predicted at 1531 nm wavelength for the fundamental TE mode and a value of threshold pump power as low as 0.2 mW has been computed.

For erbium-doped diffused waveguide we have considered the maximum erbium concentration at the surface.
For the waveguide made with indiffusion technique, we have considered the maximum contrast between the surface and the bulk. The value for refers to [9,10,15], while the value for refers to [12].
The values of pump power thresholds refer to the coupled pump power. The only exceptions are those marked with (*), where [4] reports only the absorbed pump power.
The references marked with (**) refer to theoretical works, while the others are experimental results.
