 ld of photonics comprehends the generation\, manipulation and detection of
  light (photons). Over the past decades\, it has underpinned many of the t
 echnological advances upon which we rely on a daily basis\, from our perso
 nal electronic devices and data communication channels (fibre optics)\, to
  medical instruments and lighting technologies.  Advances made in this fie
 ld depend greatly on the understanding and control we have over the light-
 matter interactions at play\, with a strong focus on integrated photonic c
 hip platforms due to their small footprint and scalability potential. One 
 of the main challenges to achieve fully integrated photonic chips deals wi
 th the emission coupling from nanoscale light sources to the on-chip photo
 nic components. Ideally\, the energy of a given light emitter should effic
 iently couple to sub-wavelength confined modes in order to fulfil scalabil
 ity requirements.  One solution is to implement metallic structures suppor
 ting surface plasmon polariton modes (i.e.\, coupled oscillations between 
 photons and the free-electrons of the metal)\, which enable confinements b
 eyond the diffraction limit of light and provide the enhancement of the em
 ission dynamics. In this talk\, I will present a variety of hybrid photoni
 c-plasmonic devices operating with down to a single nanoscale light source
 . One of our focus was the integration of single quantum emitters\, promis
 ing for quantum information technologies\, together with the plasmonic arc
 hitectures\, including colloidal quantum dots coupled to plasmonic nanoant
 ennas\, and nitrogen vacancy centers in nanodiamonds and self-assembled qu
 antum dots in semiconductor nanowires coupled to the channel plasmon polar
 iton modes supported by V-groove (VG) plasmonic waveguides.  Finally I wil
 l present our recent demonstration of a plasmonic waveguide-integrated nan
 owire laser device\, where we have placed single GaAs based semiconductor 
 nanowires at the bottom of  VG plasmonic waveguide channels. We achieve la
 sing action from a hybrid photonic-plasmonic mode supported by the NW-VG c
 onfiguration\, and observe transfer of the lasing emission into the sub-wa
 velength confined modes supported by the VGs.
