External busbars for improving current generation in multijunction solar cells
Marianna Vuorinen, Arto Aho, Elina Anttola +8
We report an improved device fabrication process employed in the development of an advanced front contact grid design employing external busbars. The advanced fabrication process r…
Electronic properties of metamorphic GaSbBi films on GaAs
Joonas Hilska, Janne Puustinen, Eero Koivusalo +1
We report on the electronic, structural, and optical properties of epitaxial GaSbBi films with varying Bi-concentration (up to 7%Bi) grown on semi-insulating GaAs(100) substrates.…
InP optical amplifiers with Euler U-bend waveguide geometry for low-loss flip-chip hybrid integration
Heidi Tuorila, Jukka Viheriälä, Lee Jae-Wung +4
We report on the development of InP-based semiconductor amplifiers with a U-bend waveguide geometry having the input and output ports on one facet only. This waveguide geometry sim…
Micro-transfer printing of GaSb optoelectronics chips for mid-infrared silicon photonics integrated circuits
Heidi Tuorila, Jukka Viheriälä, Yeasir Arafat +4
3D integration of GaSb-based gain chips on a silicon photonics platform using micro-transfer printing is demonstrated for the first time. The release process of GaSb coupons, and t…
Purcell-enhanced single-photon emission from InAs/GaAs quantum dots coupled to broadband cylindrical nanocavities
Abhiroop Chellu, Subhajit Bej, Hanna Wahl +16
On-chip emitters that can generate single and entangled photons are essential building blocks for developing photonic quantum information processing technologies in a scalable fash…
Telecom wavelength single-photon emission from quasi-resonantly excited InGaSb/AlGaSb quantum dots
Teemu Hakkarainen, Joonas Hilska, Arttu Hietalahti +10
Deterministic light sources capable of generating quantum states on-demand at wavelengths compatible with fiber optics and atmospheric transmission windows are essential for practi…
