HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L'archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau recherche, publiés ou non, émanant des établissements d'enseignement et de recherche français ou étrangers, des laboratoires publics ou privés.
We report on the design, fabrication and characterization of a reflective transmitter targeting implementation in Passive Optical Networks (PON) with Frequency Division Multiplexed Access (FDMA). It is made up of a Silicon Photonic Integrated Circuit (Si-PIC) comprising a Reflective Mach Zehnder Modulator (R-MZM) and its flip chipped CMOS Electronic Integrated Circuit (EIC) driver, the two ICs being interconnected by means of high density and low parasitic copper micro pillars. Several transmissions, in an FDMA PON context, are successfully demonstrated using 500MBaud QPSK and 16-QAM modulated subcarriers, achieving Bit Error Rate (BER) below 2.10-3. For QPSK-modulated subcarriers (respectively 16-QAM), the available access frequency bandwidth is measured to be [1-7GHz] (respectively [2-4GHz]) with an available loss budget of 9dB (respectively 5dB). Improvements of the Si-PIC are further identified to achieve compliancy with 31dB ODN loss.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
