| 中文摘要 | A high-speed submount was designed and fabricated for 40 Gb/s electroabsorption modulators ( EAMs), and characterized in the chip-level packaging and testing of an EAM device. The Al2O3-based submount contains a coplanar waveguide (CPW) for microwave signal feeding and a Ta2N thin-film resistor for impedance matching of EA modulator. Ti/ Cu/Ni/Au metal is introduced as-the CPW electrode material, and good contact with Ta2N thin-film is guaranteed accordingly. Therefore, the typical reflection coefficient of the submount is reduced to be lower than -21 dB up to 40 GHz. As a demonstration, a high-speed EA modulator was packaged by using the high-speed submount, and the small-signal modulation bandwidth was measured to be over 40 GHz. |
