heal.abstract	In the present communication we discuss recent advances in the development of Semiconductor optical amplifier (SOA)-based interferometric optical gates and their use through the implementation of functional high-speed optical systems. SOA Mach-Zehnder interferometers (SOA-MZI) show great potential for being used as fundamental building blocks in developing intelligent high speed all-optical sub-systems. In this context we discuss the development of optical systems that perform diverse and non-trivial network functionalities that find application in Optical Packet/Burst Switching networks (OPS/OBS). The use of generic building blocks to develop a variety of optical sub-systems is essential, as this avoids the requirement for custom-made technological solutions and allows for a common fabrication procedure for all subsystems. In this context, we discuss latest research on integration of arrays of such optical switches onto the same photonic chip using hybrid integration technology. The development of such arrays reduces the cost of photonic devices by sharing the packaging and pigtailing costs. By using an integrated quadruple array of SOA-MZI switches we demonstrate the frontend unit of an All-optical Label Switched node that performs clock recovery, data recovery and label/payload separation, and a scalable Time Slot Interchanger (TSI), proving the multi-functionality and processing power of such device. Both functional systems exhibit comparable performance compared to implementations using single switches with significantly lower device costs. The cost reduction offered by the integration of multiple switches on the same chip is also evident in high-speed WDM networks, where multi-wavelength regeneration can be achieved with the use of several integrated switch arrays.	en
