Heterogeneous III-V on silicon nitride amplifiers and lasers via microtransfer printing
The development of ultralow-loss silicon-nitride-based waveguide platforms has enabled the realization of integrated optical filters with unprecedented performance. Such passive circuits, when…
Micro‐Transfer‐Printed III‐V‐on‐Silicon C‐Band Semiconductor Optical Amplifiers
The micro‐transfer‐printing of prefabricated C‐band semiconductor optical amplifiers (SOAs) on a silicon waveguide circuit is reported. The SOAs are 1.35 mm in length and 40 µm in width. Dense arrays…
Ultra-Dense III-V-on-Silicon Nitride Frequency Comb Laser
A heterogeneously integrated III-V-on-silicon nitride mode-locked laser is demonstrated. The device is fabricated by microtransfer printing an InP/InAlGaAs-based multiple-quantum-well coupon. A dense…
Transfer-printing-based integration of a III-V-on-silicon distributed feedback laser.
TLDR
An electrically pumped DFB laser integrated on and coupled to a silicon waveguide circuit is demonstrated by transfer printing a 40 × 970 μm2 III-V coupon, defined on aIII-V epitaxial wafer, allowing for the very efficient use of the III- V material and the massively parallel integration of these coupons on a silicon photonic integrated circuit wafer.
III-V-on-Si photonic integrated circuits realized using micro-transfer-printing
TLDR
A promising technology, micro-transfer-printing (μTP), is discussed, which can be realized in a massively parallel manner on a wafer without substantial modifications to the SiPh process flow, leading to a significant cost reduction of the resulting III-V-on-Si PICs.
