Design of photonic integrated transmitter in a multi-project wafer run

We investigate methods for monolithically integrated multiwavelength transmitters in indium phosph ide-based materials. In particular, we focus our interest on two transmitter types. The first uses arrayed waveguide grating as wavelength selective element and the second one takes advantage ofDBR lasers that are integrated with electro-optical Mach-Zehnder modulators. In this paper we explain the operation principles and demonstrate the design process of the multiwavelength sources. We also present the mask layouts of the devices that will be fabricated in a multi-project wafer run within the EUNMPprogramme EuroPIC
