The optimum waveguide design for optical feedback reduction in a 10-Gb/s electroabsorption modulated laser has been discussed. A device with a 30-/spl mu/m-long window region exhibited as much as 10-15-dB reduction, which is verified by experimental results and the beam propagation calculation. Using a tilted waveguide with the window region, the feedback factor is reduced to as low as -40 dB. Besides low optical feedback, the tilted-and-straight modulator has a sufficient dc extinction ratio… CONTINUE READING
