Abstract
Future SONET networks operating at 10 Gbit/s and above are expected to employ high-speed optical modulators with very low chirp and high extinction ratio. Asymmetric Fabry-Perot Modulators (AFPMs) can achieve an extremely high extinction ratio by nulling the reflectance during the off-state.1 Highspeed modulation can also be obtained by utilizing the vertical cavity geometry with a low parasitic capacitance.2 In this paper, we discuss 1.5-μm operation of AFPMs with a modulation bandwidth exceeding 20 GHz.
