“…This geometry, amenable to large scale integration, is inspired by a seminal work on quantum well microlasers. 11 By combining polarization-resolved measurements and luminescence time decay analysis, we provide a comprehensive experimental investigation of the QD SE dynamics. Experimental results closely follow theoretical predictions, and we build on this agreement to discuss theoretically the b-factor for important QD excitonic complexes.…”

International audienceWe investigate the spontaneous emission (SE) of self-assembled InAs quantum dots (QDs) embedded in GaAs ridge waveguides that lay on a low index substrate. In thin enough waveguides, the coupling to the fundamental guided mode is vanishingly small. A pronounced anisotropy in the coupling to non-guided modes is then directly evidenced by normal-incidence photoluminescence polarization measurements. In this regime, a measurement of the QD decay rate reveals a SE inhibition by a factor up to 4. In larger wires, which ensure an optimal transverse confinement of the fundamental guided mode, the decay rate approaches the bulk value. Building on the good agreement with theoretical predictions, we infer from calculations the fraction β of SE coupled to the fundamental guided mode for some important QD excitonic complexes. For a charged exciton (isotropic in plane optical dipole), β reaches 0.61 at maximum for an on-axis QD. In the case of a purely transverse linear optical dipole, β increases up to 0.91. This optimal configuration is achievable through the selective excitation of one of the bright neutral excitons

“…Size reduction of semiconductor lasers have in the past enabled studies of many rich physics on an ever decreasing spatial scale and the development of many technological applications. The quantum optics and laser physics community has witnessed dramatic progress over the past few decades in making increasingly smaller lasers using pure dielectric structures such as microdisk lasers, [15][16][17] photonic wire lasers, 18 photonic crystal (PC) lasers, [19][20][21][22] or nanowire lasers. 10,[23][24][25][26] These lasers represented the smallest lasers made of pure dielectric structures, and further miniaturization becomes exceedingly challenging.…”

“…Values for between 0.3 and 0.4 have been estimated for these [108] and for the`photonic wirea lasers [109] that use a similar circular geometry. Microcavity lasers based on defects in photonic crystals or small active areas surrounded by periodic structures should appear soon and compare favourably with the existing circular geometries.…”

During the last decade, photonic crystals, also known as photonic microstructures or photonic bandgap structures, have matured from an intellectual curiosity concerning electromagnetic waves to a "eld with real applications in both the microwave and optical regime. In this review, we shall focus on progress and the prospects for semiconductor structures that mainly involve guided modes interacting with periodic structures, but we also evaluate alternative material systems and fabrication methods, e.g. those based on self-organisation. We shall go from basic concepts, via a discussion of the state of the art, to device applications. Naturally, the discussion of the applications will be more speculative, but we attempt to evaluate the real prospects o!ered by photonic crystals at optical frequencies while considering practical limitations. In doing so, we identify a variety of areas such as the combination of quantum dot light emitters with photonic crystals that seem particularly promising. We discuss the prospects for enhanced light}matter interactions in photonic crystals and the related material and design issues. Overall, the aim of this review is to introduce the reader to the concepts of photonic crystals, describe the state of the art and attempt to answer the question of what uses these peculiar structures may have.
