The complete integration of photonic devices into a CMOS process flow will enable low cost photonic functionality
within electronic circuits. BAE Systems, Lucent Technologies, Massachusetts Institute of Technology, Cornell
University, and Applied Wave Research are participating in a high payoff research and development program for the
Microsystems Technology Office (MTO) of DARPA. The goal of the program is the development of technologies and
design tools necessary to fabricate an application specific, electronic-photonic integrated circuit (AS-EPIC). The first
phase of the program was dedicated to photonics device designs, CMOS process flow integration, and basic electronic
functionality. We will present the latest results on the performance of waveguide integrated detectors, and tunable
We show high Raman gain in Silicon submicron-size strip waveguide. Using high confinement structures and pico-second pump pulses, we show 13.2-dB peak gain with 14.6-W peak pump power in a 7-mm long waveguide. The effect of free-carrier absorption is observed. We show a pico-second all-optical switch based on the Silicon waveguide, whose transmission is enhanced by the Raman gain.
Absence of relaxation oscillation in SOA fiber ring lasers is analyzed in this paper, which is always presented in actively mode- locked erbium-doped fiber (EDF) ring lasers. The super-mode competition can be effectively suppressed in SOA ring lasers due to the gain saturation of SOA. The experimental demonstrations were confirmed the above issues and good stability in a SOA mode-locked fiber ring laser without any feedback circuits was shown.
