The tilted wave concept offers the possibility to realize ultrahigh-brightness wavelength-stabilized lasers, which are important for many applications like data transmission and solid state laser pumping.
In a tilted wave laser (TWL) the narrow active waveguide is coupled to a broad second waveguide. The lasing mode leaks from the active region creating a mode in the second waveguide. The coupling of both modes results in wavelength stabilization but is also very sensitive to the design of the system. Numerical simulations are therefore very important to obtain desired properties and increase the performance of TWLs.
In our contribution we analyze tilted wave lasers numerically. The influence of design parameters on the propagating lasing eigenmodes and the emitted far field is analyzed. Our results are compared to experimental measurements of different TWLs.
