Author Affiliations +
An integrated optical device for a two component, dual beam multiplexed laser Doppler anemometer has been realized. The proton exchange and the subsequent annealing procedure in MgO:LiNbO3 yield waveguide structures with completely restored electro-optic effect, low waveguide loss, high coupling efficiency to fibers, and an increased optical damage threshold. In the device for the laser Doppler anemometry the functions of spatial filter, polarizer, beamsplitter and electro-optic modulators are integrated on a single chip. The present paper investigates the use of a specific integrated optical device as a next phase of evolution in laser Doppler anemometry.
