Abstract : In this effort, novel techniques based on semiconductor traveling wave optical amplifiers were demonstrated. These devices provide potential solutions to the challenges in wavelength-division multiplexing - time-division multiplexing (WDM-TDM) networks and millimeter wave communication systems. The semiconductor traveling wave optical amplifier provides a self-stabilized source of multiple optical wavelengths for WDM and low phase noise millimeter-wave and terahertz signals for wireless telecommunications and TDM. A single-stripe semiconductor traveling wave amplifier (STWA) was fabricated that demonstrated four-wavelength, 1O-Gbit/sec picosecond pulse generation. The advantages of this approach include self-stabilization and "sharing" a common RF and DC driving source among each wavelength channel. This effort also investigated ultrafast optical pulse generation using intracavity heterodyning of multiple phase-locked wavelengths and also simulated the temporal modulation generated within the multiwavelength laser.
