Tailored Probe Tips for Atomic Force Microscopes
Tailored Probe Tips for Atomic Force Microscopes

August, 2016. IPQ/IMT/APH researchers demonstrate a novel kind of custom-made probe tips for Atomic Force Microscopy (AFM). The tips are fabricated by direct-write 3D lithography, building upon experience gained from research in photonic integration. This approach offers great potential for wafer-scale fabrication of custom AFM probes. The work has been published as a featured article in Applied Physics Letters (APL) and is advertised on the title page.

Silicon-plasmonic internal-photoemission detector for 40  Gbit/s data reception

July, 2016. Publication in Optica: IPQ/IMT researchers demonstrate a novel class of high-speed and ultra-compact plasmonic photodetectors on the silicon platform operating at a wavelength of 1550 nm. The detection principle relies on internal photoemission at metal-silicon interfaces, enabling reception of optical data at rates up to 40 Gbit/s while the device footprint is below 1 µm². The new silicon-plasmonic photodetectors could lead to ultra-compact chip-to-chip interconnects operating at high data rates.

Nature Communications: Lasing in silicon–organic hybrid waveguides

March, 2016: Publishing in the well-known journal Nature Communications, IPQ/IMT researchers demonstrate a novel class of infrared lasers that can be fabricated on the silicon photonic platform. The lasers rely on the silicon-organic hybrid (SOH) approach and combine nanophotonic silicon-on-insulator (SOI) waveguides with dye-doped organic cladding materials that provide optical gain. We show pulsed laser emission at 1310 nm with peak output powers of more than 1 W. The SOH approach offers enormous potential for efficient mass-production of silicon photonic biosensors.
