Low optical loss electrical isolation for multi-section monolithic GaSb-based photonic circuits
Md Ajwaad Zaman Quashef, Nouman Zia, Jukka Viheriälä +1
Monolithic photonic integrated circuits (PICs) platforms exploiting III-V materials combine passive and active waveguide structures in multi-section optoelectronic device architect…
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…
