Abstract
An integrated optical transmitter includes a modulator drive circuit in communication with a modulator, and a laser drive circuit in communication with a laser. The modulator receives laser light from the laser and modulation control signals from the modulator drive circuit, and outputs modulated optical signals in a direction normal to the substrate surface. The transmitter is integrated by securing the laser to the modulator using flip chip technology. The laser includes a vertical cavity, and is optically aligned with the horizontal coupling surface of the modulator during the flip chip process.
