Sub-kHz-linewidth external-cavity laser (ECL) with SiN resonator used as a tunable pump for a Kerr frequency comb
Pascal Maier, Yung Chen, Yilin Xu +11
Combining optical gain in direct-bandgap III-V materials with tunable optical feedback offered by advanced photonic integrated circuits is key to chip-scale external-cavity lasers…
3D-printed facet-attached optical elements for connecting VCSEL and photodiodes to fiber arrays and multi-core fibers
Pascal Maier, Yilin Xu, Mareike Trappen +11
Multicore optical fibers and ribbons based on fiber arrays allow for massively parallel transmission of signals via spatially separated channels, thereby offering attractive bandwi…
3D-printed facet-attached optical elements for beam shaping in optical phased arrays
Stefan Singer, Yilin Xu, Sebastian Tobias Skacel +10
We demonstrate an optical phased-array (OPA) equipped with a 3D-printed facet-attached element for shaping and deflection of the emitted beam. The beam shaper combines freeform ref…
3D-M3: High-spatial resolution spectroscopy with extreme AO and 3D printed micro-lenslets
Theodoros Anagnos, Mareike Trappen, Blaise C. Kuo Tiong +20
By combining IFS with ExAO we are now able to resolve objects close to the diffraction-limit of large telescopes, exploring new science cases. We introduce an IFU designed to coupl…
Superconducting Nanowire Single-Photon Detector (SNSPD) with 3D-Printed Free-Form Microlenses
Yilin Xu, Artem Kuzmin, Emanuel Knehr +6
We present an approach to increase the effective light-receiving area of superconducting nanowire single-photon detectors (SNSPD) by means of free-form microlenses that are printed…
An innovative integral field unit upgrade with 3D-printed micro-lenses for the RHEA at Subaru
Theodoros Anagnos, Pascal Maier, Philipp Hottinger +26
In the new era of Extremely Large Telescopes (ELTs) currently under construction, challenging requirements drive spectrograph designs towards techniques that efficiently use a faci…
Diffraction-limited integral-field spectroscopy for extreme adaptive optics systems with the Multi-Core fiber-fed Integral-Field Unit
Sebastiaan Y. Haffert, Robert J. Harris, Alessio Zanutta +31
Direct imaging instruments have the spatial resolution to resolve exoplanets from their host star. This enables direct characterization of the exoplanets atmosphere, but most direc…
3D-Printed Optics for Wafer-Scale Probing
Mareike Trappen, Matthias Blaicher, Philipp-Immanuel Dietrich +5
Mass production of photonic integrated circuits requires high-throughput wafer-level testing. We demonstrate that optical probes equipped with 3D-printed elements allow for efficie…
