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…
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 sp…
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 w…
Fast Recovery Dynamics of GaSbBi-based SESAMs for high-fluence operation
Maximilian C. Schuchter, Joonas Hilska, Markus Peil +4
Modelocked lasers operating at 2-3 um wavelength region are interesting for various spectroscopic applications. To this end, GaSb-based semiconductor saturable absorber mirrors (SE…
