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…
Hybrid Electro-Optic Modulator Combining Silicon Photonic Slot Waveguides with High-k Radio-Frequency Slotlines
Sandeep Ummethala, Juned N. Kemal, Ahmed S. Alam +10
Electro-optic (EO) modulators rely on interaction of optical and electrical signals with second-order nonlinear media. For the optical signal, this interaction can be strongly enha…
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…
Mode-locked laser timing jitter limitation in optically enabled, spectrally sliced ADCs
Andrea Zazzi, Juliana Müller, Sergiy Gudyriev +5
Novel analog-to-digital converter (ADC) architectures are motivated by the demand for rising sampling rates and effective number of bits (ENOB). The main limitation on ENOB in pure…
Silicon-Organic Hybrid (SOH) Mach-Zehnder Modulators for 100 GBd PAM4 Signaling With Sub-1 dB Phase-Shifter Loss
Clemens Kieninger, Christoph Füllner, Heiner Zwickel +8
We report on compact and efficient silicon-organic hybrid (SOH) Mach-Zehnder modulators (MZM) with low phase shifter insertion loss of 0.7 dB. The 280 m-long phase shifters feat…
Hardwire-Configurable Photonic Integrated Circuits Enabled by 3D Nano-Printing
Tobias Hoose, Matthias Blaicher, Juned Nassir Kemal +7
Photonic integrated circuits (PIC) currently rely on application-specific designs that are geared towards a particular functionality. Development of such application-specific PIC r…
