We demonstrate the heterogeneous integration of GaInAsSb-GaSb photodiodes on 220 nm SOI photonic integrated circuits (PICs) using the micro-transfer-printing (μTP) technology, for operation in the short-wave infrared (SWIR) wavelength region. Utilizing an evanescent coupling scheme between a silicon waveguide and a III-V structure, the device exhibits a room temperature responsivity of 1.23 and 1.

Two types of pre-fabricated III-V semiconductor optical amplifiers (SOAs) with a photoluminescence (PL) peak around 1500 nm and 1550 nm are micro-transfer printed on two silicon laser cavities. The laser cavities are fabricated in imec's silicon photonics (SiPh) pilot line on 200 mm silicon-on-insulator (SOI) wafers with a 400 nm thick silicon device layer.

Both single device and arrayed printing is demonstrated. The photodiodes exhibit dark currents below 20 pA and waveguide-referred responsivities of up to 0.

Transfer printing is a promising micromanipulation technique that allows the heterogeneous integration of optical and electronic components realized on their native substrate onto a target substrate with efficient use of the source material, in a way that can be scaled to parallel manipulation and that allows mixing components from different sources onto the same target. We pre-process transfer printable etched facet Fabry-Pérot lasers on their native InP substrate, transfer print them into a trench defined in an SOI photonic chip and post-process the printed lasers on the target substrate.
