DESCRIPTION:Multi-wavelength lasers have emerged as a promising solution fo
 r a range of applications: from sensing to high-frequency signal generatio
 n or all-optical processing. For instance\, they are an appealing solution
  to generate mm-wave or THz signals: besides the reduce footprint or the l
 ack of required alignment\, the coupling between modes leads to lower nois
 e level. However\, lasing is still a “winner takes it all” process\, t
 hus simultaneous emission at multiple wavelengths can be a challenging tar
 get to reach. A rather careful design or a precise control mechanism are t
 ypically required.\n\nIn this talk\, I will briefly review demonstrated sc
 hemes to implement multi-wavelength lasers on Photonic ICs\, with a partic
 ular focus on laser designs compatible with (active) generic foundry platf
 orms. I will discuss the difficult trade-off between flexibility\, tunabil
 ity and stability\, and highlight the approach we chose relying on a phase
 -controlled optical feedback loop. Finally\, I will present some of our re
 cent results exploiting such multi-wavelength lasers for new applications 
 such as spectral multiplication of frequency combs and wavelength conversi
 on.\n\nSpeaker(s): Martin Virte\, \n\nRoom: MC603\, Bldg: McConnell Engine
