Abstract: Simulations were carried out to determine the optical properties of 2 different layer structures which have been used in quantum well intermixed devices. The supported modes, effective refractive indices and optimal device dimensions prior to intermixing were reported. 1.5 micrometer ridge waveguides with 600 micrometer bend radii are shown to be suitable for minimizing loss. A first approximation to the intermixed structures were also simulated. An Asymmetric Mach-Zehnder Interferometer (AMZI) fabricated using a sputtered SiO2 Quantum Well Intermixing (QWI) process was also characterized. A 100 GHz channel spacing with an extinction ratio up to 16 dB was observed. Tuning of the device was achieved using current injection. A 0.45 nm tuning range was achieved at 15 mA of injected current. The design of a monolithically integrated all optical binary half-adder is also presented, with physical dimensions based on the results of the previous simulations.
