Freeform terahertz structures fabricated by multi-photon lithography and metal coating
Pascal Maier, Alexander Kotz, Joachim Hebeler +10
Direct-write multi-photon laser lithography (MPL) combines highest resolution on the nanoscale with essentially unlimited 3D design freedom. Over the previous years, the groundbrea…
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…
