Design and simulation for the fabrication of integrated semiconductor optical logic gates
… (SOAs) in each arm and includes straight ridge waveguides, ridge waveguide bends, and multimode interference (MMI) devices. We use beam propagation method (BPM) to model, design and optimize dilute ridge waveguides, MMIs, and asymmetric twin waveguide (ATG) adiabatic taper couplers. We assess …

Photonic integrated circuits for optical logic applications
… 1550 nm are vertically integrated with passive waveguides using the asymmetric twin waveguide technique and the SOAs are placed in a Mach-Zehnder interferometer (MZI) configuration. By sending in high-intensity pulses, the gain characteristics, phase-shifting, and refractive indices of the SOA …

Indium phosphide based integrated photonic devices for telecommunications and sensing applications
… that are optically coupled to the passive waveguides using the asymmetric twin waveguide technique. The device is grown and fabricated monolithically and carrier-dependent optical interference is demonstrated at the 1.55 [mu]m wavelength. The tunable diode laser is designed to operate in …

Integrated spot size converters for InP based photonic systems
… and characterization of SSCs based on an asymmetric twin waveguide (ATG) at a wavelength of 1.55 μm are the main elements of this dissertation. It is theoretically and experimentally shown that a passive ATG facilitates a polarization filter mechanism. A reproducible InP process guideline …
