We report results of an improved hybrid optical transmitter suitable for use in microwave communication systems. Based on a double up-conversion technique, a 1.3 micrometers wavelength semiconductor diode laser is actively mode-locked, and its output is externally modulated by a lithium niobate Mach-Zehnder amplitude modulator to generate a transmitter output from 19 GHz to 21 GHz. Following a brief review of recent table top system measurements and motivation, we show a second generation engineering scheme for packaging the mode-locked source components. The initial performance results of this source are -34.2 dBm(e) mode-locked output power at 13.1 GHz, with an input rf power of 14.5 dBm(e); RIN is measured at -106.5 dBc(e)/Hz.
