TL;DRAbstract

In this program, we investigated the fabrication and optical characterization of a photonic integrated circuit (PIC) designed for telecommunication applications using ultrafast (> 100Gbits/s) optical logic. The basic components in the PIC are active components, such as semiconductor optical amplifiers (SOAs), integrated with passive, light-routing waveguides. Optical switching is accomplished by embedding the amplifiers within the arms of Mach-Zehnder interferometers (MZIs), whereas power splitting of propagating signals is carried out within multimode interferometers (MMIs). Figure 1 shows a schematic of the basic unit cell under investigation.
