Single crystal diamond gain mirrors for high performance vertical external cavity surface emitting lasers

Niels Quack, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Pascal Gallo, Gergely Huszka, Mehdi Naamoun

We report on the design, fabrication and optical performance of gain mirrors in single crystal diamond substrates for vertical external cavity surface emitting lasers (VECSELs). VECSELs have gained attention recently due to their potential for high emissio ...

1.55-mu m wavelength wafer-fused OP-VECSELs in flip-chip configuration

Elyahou Kapon, Alexandru Mereuta, Andrei Caliman, Pascal Gallo

Optically-pumped vertical external cavity surface emitting lasers (VECSELs) based on flip-chip gain mirrors emitting at the 1.55-mu m wavelength range are reported. The gain mirrors employ wafer-fused InAlGaAs/InP quantum well heterostructures and GaAs/AlA ...

Self-formation of hexagonal nanotemplates for growth of pyramidal quantum dots by metalorganic vapor phase epitaxy on patterned substrates

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Romain Carron, Pascal Gallo, Alessandro Surrente

We demonstrate the self-formation of hexagonal nanotemplates on GaAs (111)B substrates patterned with arrays of inverted tetrahedral pyramids during metal-organic vapor phase epitaxy and its role in producing high-symmetry, site-controlled quantum dots (QD ...

Exciton dynamics in a site-controlled quantum dot coupled to a photonic crystal cavity

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Alexey Lyasota, Clément William Tendaï Jarlov

Exciton and cavity mode (CM) dynamics in site-controlled pyramidal quantum dots (QDs), integrated with linear photonic crystal membrane cavities, are investigated for a range of temperatures and photo-excitation power levels. The absence of spurious multi- ...
