Validation and extension of the PAWS Zemax model as a first step in the development of a Compact Arrayed Waveguide Stacked Multi-Object Spectrograph (CAWSMOS)
Fabienne Mangelsdorff, Andreas Stoll, Lars Zimmermann +4
The linear size of a bulk optical astronomical spectrograph scales with the diameter of the primary mirror of the corresponding telescope. As modern telescopes continue to increase…
H2020-SPACE-ORIONAS Miniaturized optical transceivers for high-speed optical inter-satellite links
L. Stampoulidis, A. Osman, I. Sourikopoulos +10
The European H2020-SPACE-ORIONAS project targets the development of optical transceiver and amplifier integrated circuits and modules applicable to high-speed and compact laser com…
Dual-polarization multiplexing amorphous Si:H grating couplers for silicon photonic transmitters in the photonic BiCMOS backend of line
Galina Georgieva, Christian Mai, Pascal M. Seiler +2
We report on polarization combining 2D grating couplers (2D GCs) on amorphous Si:H, fabricated in the backend of line of a photonic BiCMOS platform. The 2D GCs can be used as an in…
Cross-polarization effects in sheared 2D grating couplers in a photonic BiCMOS technology
Galina Georgieva, Karsten Voigt, Christian Mai +3
We investigate numerically and experimentally sheared 2D grating couplers in a photonic BiCMOS technology with a focus on their splitting behavior. Two realization forms of a waveg…
64 GBd DP-Bipolar-8ASK Transmission over 120 km SSMF Employing a Monolithically Integrated Driver and MZM in 0.25-um SiGe BiCMOS Technology
Gilda Raoof Mehrpoor, Carsten Schmidt-Langhorst, Benjamin Wohlfeil +13
We demonstrate 64 GBd signal generation up to bipolar-8-ASK utilizing a single MZM, monolithically integrated with segmented drivers in SiGe. Using polarization multiplexing, 300-G…
A BaTiO3-Based Electro-Optic Pockels Modulator Monolithically Integrated on an Advanced Silicon Photonics Platform
Felix Eltes, Christian Mai, Daniele Caimi +10
To develop a new generation of high-speed photonic modulators on silicon-technology-based photonics, new materials with large Pockels coefficients have been transferred to silicon…
Vertical optical ring resonators fully integrated with nanophotonic waveguides on silicon-on-insulator substrates
Abbas Madani, Moritz Kleinert, David Stolarek +3
We demonstrate full integration of vertical optical ring resonators with silicon nanophotonic waveguides on silicon-on-insulator substrates to accomplish a significant step towards…
Numerical Simulation of Grating Couplers for Mode Multiplexed Systems
B. Wohlfeil, S. Burger, C. Stamatiadis +4
A numerical investigation of a two dimensional integrated fiber grating coupler capable of exciting several LP fiber modes in both TE and TM polarization is presented. Simulation r…
