Abstract
We have demonstrated a semiconductor optical amplifier and electroabsorptio n modulator monolithically integrated with a novel dual-waveguide spot-size converter at the input for low-loss coupling to planar lightguide circuit silica waveguides or cleaved single-mode optical fiber. These devices exhib it greater than 10 dB fiber-to-fiber gain, output power of +4 dBm, 3-dB mod ulation bandwidth of 6 GHz, and modulator extinction ratios of 20 dB de and 14.4 dB RF for a 2.4-V-PP drive.
