Analysis of soliton waveguides in lithium niobate at 405nm wavelength

Recently it was shown that soliton waveguides in lithium niobate can be recorded very fast at 405 nm wavelength. We analyze the mode profile of soliton waveguides recorded at 405 nm using different external electric fields and different writing beam polarizations. We discuss the advantages of recording at this wavelength when comparing with the recording process at 532 nm.
