Measurement Tool Helps Optimize Semiconductors for Optoelectronics
To enable efficient, complete characterization of semiconductors, scientists at Helmholtz Zentrum Berlin developed a method that records 14 different parameters of transport properties in negative and positive charge carriers in a single measurement. The new method, which the researchers call Constant Light-Induced Magneto-Transport (CLIMAT), is based on the Hall effect and could help scientists accurately assess new materials for optoelectronic devices in far less time than existing methods.

Integrated Photonics for Quantum Computing
Tue, May 28, 2024 10:00 AM - 11:00 AM EDT
Realizing photonic quantum technologies, such as an optical quantum computer or a quantum communication link between distant superconducting qubits, will require the development of novel photonic components. Monolithic silicon or silicon nitride photonic platforms are falling short with respect to the requirements of the quantum domain, and it is envisioned that a hybrid solution is needed. In this talk, Christian Haffner of IMEC shortly discusses what hybrid solutions the silicon photonic platform can offer in terms of detectors, sources, and modulators. His primary focus lies on the electro-optical modulator covering the requirements that the quantum world enforces. He compares the classical and quantum theoretical framework, and sketches out what performance metrics a quantum electro-optical modulator needs to fulfill.
