A broadband 1.5μm GaInAsP travelling-wave laser ampli-fier has been realised with angled facets instead of anti-reflection coatings. The measured signal gain for the TE mode is 19dB at the wavelength around 1.49μm with a 2dB gain ripple over one free spectral range and a 3dB band-width of 55 nm. The estimated residual modal reflectivity is 0.2%.
