  • Polarization independent and temperature tolerant AWG based on a silicon nitride platform
    Optics Letters, 2020
    Co-Authors: Sylvain Guerber, Carlos Alonso-ramos, Nathalie Vulliet, Delphine Marris-morini, Frederic Boeuf, Xavier Le Roux, Eric Cassan, Laurent Vivien
    Abstract:

    Polarization tolerant optical receiver is a key building block for the development of wavelength division multiplexing (WDM) based high-speed optical data links. However, the design of polarization independent demultiplexer (DEMUX) is not trivial. In this work, we report on the realization of a polarization tolerant arrayed waveguide grating (AWG) on a 300-mm silicon nitride (SiN) photonics platform. By introducing a series of individual polarization rotators in the middle of the waveguide array, the polarization dependence of the AWG has been substantially reduced. Insertion losses below 2.2dB and a Crosstalk Level better than-29dB has been obtained for TE and TM polarizations on a four channel coarse AWG. The AWG temperature sensitivity has also been evaluated. Thanks to the low thermo-optical coefficient of SiN, a thermal shift below 12pm/°C has been demonstrated.

  • Design and Integration of an O-band Silicon Nitride AWG for CWDM Applications
    2017
    Co-Authors: Sylvain Guerber, Carlos Alonso-ramos, Diego Perez-galacho, Xavier Leroux, Nathalie Vulliet, Sébastien Cremer, Delphine Marris-morini, Frederic Boeuf, Laurent Vivien, Charles Baudot
    Abstract:

    Experimental demonstration of an O-band four channel CWDM silicon nitride AWG is reported. Specificity of low order array has been explored through multiple devices among which insertion loss below 2.3dB, Crosstalk Level as high as 37dB and polarization insensitive spectral response flattening is obtained.

  • The influence of aperture size and shape on Crosstalk Level in free-space grating demultiplexers for WDM networks
    IEEE Photonics Technology Letters, 1996
    Co-Authors: E.g. Churin, Polina Bayvel, John E. Midwinter, A. M. Hill
    Abstract:

    A simple method is presented to calculate Crosstalk caused by aberrations and diffraction at the aperture edges in free-space grating demultiplexers for wavelength-division multiplexed (WDM) communication systems. The influence of circular and square aperture sizes is described for ideal and aberrated optical systems. It is shown that aperture enlargement is not critical to aberrations whilst providing significant Crosstalk reduction. The minimum Crosstalk value is obtained when the dispersion plane is parallel to the diagonal of the square aperture. -60 dB Crosstalk is attainable for moderately aberrated systems with 80 channels (0.5 nm spacing) in the range 1530-1570 nm.
