QPIC-2

Quantum Photonic Integrated Components

For the cooling and precise control of ions in ion trap quantum processors, lasers with extremely narrow linewidths and high stability are required. Today, these lasers are often still set up as complex systems on optical tables next to the ion traps. The QVLS-iLabs project QPIC aims to transfer this technology into compact and robust modules.

In the second project phase (QPIC-2), highly integrated laser sources are being developed that are specifically tailored to the requirements of ion trap quantum computers. Since the required wavelengths are often in the blue and UV spectral range and hardly any compact solutions have existed for this purpose to date, this represents a key challenge for miniaturization.

Building on the successful results of the first phase, blue distributed-feedback laser diodes are being further developed. In addition, Photonic Crystal Surface-Emitting Lasers (PCSELs) are being investigated as a novel approach that can combine very narrow linewidths with high intensity. The goal is to demonstrate compact, application-ready laser modules for wavelengths between 397 nm and 461 nm.
