On-chip tunable perovskite laser in the visible/near-infrared range

The availability of a tunable laser source in the visible and near-infrared (NIR) range is crucial for a variety of high-impact applications, such as frequency-modulated continuous wave LiDAR, optical coherence tomography, quantum photonics, and molecular spectroscopy. Despite the demand, current solutions for tunable lasers in these wavelength ranges remain limited, both in terms of availability and performance. Metal halide perovskite thin films are emerging as highly promising materials for such applications due to their exceptional optical properties, ease of processing, and compatibility with a wide range of substrates and photonic platforms. In PEROTUNE, we aim to demonstrate a mode-hop free (MHF) tunable laser by leveraging the unique properties of perovskite materials combined with innovative design strategies to enable continuous tuning without mode hopping. This approach capitalizes on the tunability and high optical gain of perovskites in the visible/NIR spectrum, addressing current limitations in laser source technology. By adopting advanced integration techniques, the proposed design will deliver compact, efficient, and versatile laser sources suitable for a wide range of applications. In particular, this breakthrough innovation has the potential to impact fields ranging from medical diagnostics and environmental monitoring to advanced manufacturing and telecommunications, opening new doors for next generation photonic devices
