Silicon Photonics Wavelength-Independent C-Band Tunable Optical Filter With Feasible Thermal Tuning Requirements
Saif Alnairat, Benjamin Wohlfeil, Stevan Djordjevic +1
A filter design based on Vernier microrings and wideband directional couplers is proposed for ASE noise suppression in next generation DCI applications. We demonstrate a 40 nm FSR-…
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…
hp-finite-elements for simulating electromagnetic fields in optical devices with rough textures
S. Burger, P. Gutsche, M. Hammerschmidt +5
The finite-element method is a preferred numerical method when electromagnetic fields at high accuracy are to be computed in nano-optics design. Here, we demonstrate a finite-eleme…
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…
