Time-domain optical coherence tomography at 2 using GaSb-based broadband superluminescent diode
Ifte Khairul Aam Bhuiyan, Alejandro Martinez Jimenez, Ramona Cernat +8
We report a time-domain optical coherence tomography (TD-OCT) system operating in the 2 spectral region, enabled by a GaSb-based superluminescent diode (SLD). The spe…
Design of broadband optical gain in GaSb-based waveguide amplifiers with asymmetric quantum wells
Ifte Khairul Alam Bhuiyan, Joonas Hilska, Markus Peil +2
A design strategy for achieving broadband optical gain in GaSb-based semiconductor amplifiers operating beyond 2 μm is presented. By employing asymmetric GaInSb/AlGaAsSb quantum we…
Nonlinear Optical Microscopy of Semiconductor Metal-Nanocavities
Riya Varghese, Shambhavee Annurakshita, Yaraslau Tamashevich +13
We use second and third harmonic generation microscopy to investigate the nonlinear optical response of GaAs nanocavities embedded in a gold film and compare them to bare GaAs nano…
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…
