Silicon Nitride C-Band Grating Coupler with Reduced Waveguide Back-Reflection Using Adaptively Corrected Elliptical Grates
Ibrahim Ghannam, Florian Merget, Jeremy Witzens
We present experimental results for a fully etched C-band grating coupler with reduced back reflection fabricated in an 800 nm silicon nitride platform. Back-reflections are reduce…
Focusing Optical Phased Array for Optically Enabled Probing of the Retina with Subcellular Resolution
Pedram Hosseini, Prachi Agrawal, Alireza Tabatabaei Mashayekh +3
We present a silicon-nitride-based optical phased array with built-in focusing and steering capability, that operates at 522 nm and is aimed at complementing a micro-electrode arra…
External Cavity 637-nm Laser with Increased RSOA-to-PIC Alignment Tolerance and a Filtered Sagnac-Loop Reflector with Single Output Waveguide
Georgios Sinatkas, Arijit Misra, Florian Merget +1
The design of a 637-nm wavelength, photonic-integrated-circuit-based external cavity laser (PIC-based ECL) aimed at quantum technology applications is presented together with first…
An efficient singlet-triplet spin qubit to fiber interface assisted by a photonic crystal cavity
Kui Wu, Sebastian Kindel, Thomas Descamps +6
We introduce a novel optical interface between a singlet-triplet spin qubit and a photonic qubit which would offer new prospects for future quantum communication applications. The…
Two-dimensional photonic crystal cavities in ZnSe quantum well structures
Siqi Qiao, Nils von den Driesch, Xi Chen +7
ZnSe and related materials like ZnMgSe and ZnCdSe are promising II-VI host materials for optically mediated quantum information technology such as single photon sources or spin qub…
Chip-to-chip ODDM network with optically enabled equalization
Andrea Zazzi, Jeremy Witzens
We propose and model an optical communication scheme for short distance datacom links based on the distribution of information across a wide comb spectrum. This modulation format,…
Broadband, Temperature Tolerant and Passively Biased Resonantly Enhanced Mach-Zehnder Modulators
S. Romero-García, A. Moscoso-Mártir, J. Nojic +5
We describe a resonantly enhanced Mach-Zehnder modulator (MZM) that can be operated over a wide temperature range of 55C without being actively biased, while providing a significan…
