Abstract
Advanced optical networks will employ high speed optical modulators with extremely low chirp and high extinction ratio. Asymmetric vertical-cavity Fabry-Perot modulators (AFPMs) can achieve essentially infinite extinction ratio by nulling the reflectance during the off-state. High speed modulation can also be obtained by utilizing the vertical cavity geometry with low parasitic capacitance. Recently, 37 GHz AFPMs with 20 dB contrast and 1.5 dB insertion loss have been demonstrated at 864 nm.1 In this paper, we demonstrate 1535 nm operation of AFPMs based on OMCVD grown InP/InGaAsP mirror stacks and a AlInGaAs/InGaAs quantum well region.
