Abstract

Very-low-driving-voltage (less than 1 Vpp) electroabsorption modulators operating at 40-Gbit/s NRZ large-signal modulation have been fabricated using strained InGaAlAs/InAlAs multiple quantum wells (MQWs). The optimum structure has been discussed with strain magnitude in the wells as a parameter, based on a figure of merit that is defined as the ratio of 3 dB bandwidth to the driving voltage. Blue chirp operation for low insertion loss with prebias has been demonstrated in addition to polarization insensitivity.
