Photonic integrated transceiver for hybrid PONs

This paper presents a photonic integrated tunable transceiver for Wavelength Division Multiplexing (WDM) Passive Optical Networks (PONs) that supports higher order modulation format such as Quadrature Phase Shift Keying (QPSK). The architecture of the transceiver will be presented and divided into blocks. Then, the design of each block will be discussed. At the end one can find laboratory results that validate the concept of the used architecture.
