This project deals with guided wave devices realized on GaAs and InP substrates.

Three main axes are investigated :
  • quantum dot based (QD) edge emitting lasers for access and metropolitan area networks
  • quantum dot based amplifiers and electro-optic modulators for all-optical signal processing
  • novel concepts in guided wave devices, in particular the use of metamaterials for new optical functions.
  • GuiWac QDLas : Quantum dot based lasers
    The unique properties related to the three dimension confinement of charge carriers in self assembled quantum dots are exploited to develop high bit rate (10 Gbit/s) directly modulated laser sources with low threshold current, low phase-amplitude coupling factor -Henry factor-, temperature insensitive and feedback immune to comply with recent access and metropolitan area network standards.
    The QD broad optical gain spectrum, ultrafast gain dynamics and small amplified spontaneous emission (ASE) coupled to the propagating mode are moreover assets for sub-picosecond and low jitter pulse generation using monolithic mode locked lasers. Applications including frequency comb generation for 10 Gbit/s WDM transmission at 1.3 and 1.55 µm, or microwave signal generation for radio-over-fibre are being investigated.

    VCDev QDSign : Guided wave devices for signal processing
    Quantum dot based gain media exhibit enhanced non-linear effects, well suited e.g. for all optical signal processing. Very efficient four wave mixing in optical amplifiers is exploited to modify the light group index, which allows the achievement of controllable optical delay lines at room temperature.
    Enhanced electro-optic Pockels effect has been demonstrated in QD based waveguides, over a very wide optical bandwidth opening the way to the achievement of efficient wide band electro-optic modulators.

    Metaphot: Novel concepts in guided wave optics : ‘metaphotonics’ for telecom applications:
    The use of left-handed metamaterials on III-V substrates is very attractive as it should be possible to incorporate gain layers to compensate for the optical losses arising from the metallic resonators. It should indeed be possible to use a guided wave configuration with a core waveguide made of quantum wells or dots where gain is achieved by electrical injection.
