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…
