Using standard photolithographic techniques, the waveguide pattems were replicated onto LiNbOa substrates. ... Ti diffusion seems to eliminate the sharp edges and the loss contribution associated with the quasi-periodic staircase structure. ... Based on calculations with the multilongitudinal mode laser diode rate equation, where the injection current is sinusoidal ... and a 3-dB bandwidth of ~3 GHz with an Al traveling- wave electrode. insertion losses including coupling, reflection, andanbsp;...
