On behalf of the IEEE Photonics Society, I want like to welcome you to the 2013 Summer Topical Meetings held on the beautiful Big Island of Hawaii. With more than 20 years of tradition, the IEEE Summer Topicals are the premier conferences for emerging fields in photonic science, device technologies, and applications. The conferences are held to create the opportunity to learn about exciting new topics...
This talk will review the most recent progress on metallic cavity nanolasers with sub-wavelength size cavities, especially the efforts towards the first demonstration of CW operation at room temperature under electrical injection.
Numerical and experimental studies of few-modes Erbium-doped fibers amplifiers suitable for mode-division multiplexing are presented. Based on simulations, fiber with tailored Erbium spatial distribution has been designed to support and amplify 6 spatial modes. Realizations are presented and discussed.

We report our recent experimental and theoretical development on metal-cavity surface-emitting quantum-dot microlasers. Room-temperature operation is achieved for devices with diameters close to one wavelength. The experimental data agrees well with our developed theoretical model.
Record low dissipated energy of 118 to 56 fJ/bit is reported for our VCSELs operating error-free at 40, 30, and 25 Gb/s across 50, 500, and 1000 m of MMF, respectively.
Directly modulated VCSELs operating at 40Gb/s are required for next generation optical interconnect standards. Using a refined high-speed design we demonstrate GaAs-based VCSELs that operate error-free at 47Gb/s at 25°C, and 40Gb/s at 85°C.
Two-dimensional coherently coupled vertical cavity surface emitting laser (VCSEL) arrays have long been pursued for narrow divergence and high brightness applications. We discuss both top and bottom-emitting coherent VCSEL arrays that can operate in the in-phase mode. The key to their operation is strongly coupled leaky-mode operation, which can be achieved using ion implantation to define a periodically...
We have transferred epitaxial layers between wafers and we have fabricated VCSELs on new host substrates. This procedure facilitates more advanced VCSEL designs by providing processing access to both sides of the epitaxial layers.
CMOS-compatible III–V/Si vertical-cavity surface-emitting lasers (VCSELs) based on a double set of photonic crystal reflectors are demonstrated, showing single-mode continuous-wave operation at 1.55-µm with thresholds in the sub-mW range. The natural propensity of these VCSEL devices for achieving a wide range of functionality is discussed.
Quantum dot semiconductor lasers have been the subject of significant investigation for many years. In part this is for potential applications based on desirable properties when compared with traditional quantum well-based lasers such as ultra-low threshold current density and reduced temperature sensitivity [1]. The most common technique for quantum dot growth is the self-assembly technique, in which...
We report here electrically-pumped membrane reflector surface-emitters on silicon based on transferred InGaAsP QW structures sandwiched in between two single-layer Fano resonance photonic crystal membrane reflectors on silicon substrate.
Laterally-coupled-cavity VCSELs using bow-tie shape oxide aperture is demonstrated. The lasing characteristics show clear evidence of coherent lateral coupling. High-speed push-pull-modulation free from relaxation oscillation frequency is expected via spatially altering the transverse mode distribution.
