Infrared photonics for healthcare: A roadmap for proactive and predictive health management
Borislav Hinkov, Johannes Kunsch, Werner Mäntele +82
The field of infrared (IR) photonics is currently undergoing remarkable progress, moving rapidly towards practical sensing applications demanded by medical therapy and diagnostics…
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…
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…
