Paper Abstract

In order to overcome the bandwidth limitations of lumped element electro-optic modulators, a velocity matched traveling wave modulator has been designed, built and is being tested. The modulator, which utilized two lithium tantalate crystals in a 12.5Q transmission line structure, had a switching voltage of 12 volts. Preliminary data taken using a CW krypton laser and a 1 Gbps data source indicates that the driver rather than the modulator is limiting the response of the system. A 2 Gbps data source and a 2 Gpps optical input is being prepared for further testing. When operating at 2 Gbps, the modulator should require 25 watts of operating power in order to achieve full switching.
