Case Study

Broadband Light Modulation Capability of Chromium Iodide Thin Films

Li, Ning, et al. Nanophotonics, 2023, 12(23), 4329-4337.

In this work, chromium iodide (CrI3) thin films were prepared and the broadband linear and nonlinear absorption of CrI3 thin films were studied, verifying the broadband light modulation capability of CrI3 thin films.
Preparation and characterization of CrI3 thin films
· The CrI3 film utilized in the experiment was produced using the spin-coating technique. A solution was made by dissolving commercial CrI3 powder in alcohol, which was then applied to create the film.
· Measurements of both linear and nonlinear absorption, as well as ultrafast response of the CrI3 film, revealed its ultrafast carrier dynamics and substantial broadband saturation absorption in the mid-infrared range. Thanks to the remarkable nonlinear optical absorption properties of the CrI3 film, robust pulsed fiber lasers operating in the 1.5 μm and 2.8 μm wavelengths have been successfully developed. The mode-locked operation at a wavelength of 1567.17 nm exhibited exceptional stability, with a signal-to-noise ratio (SNR) of 92.4 dB and a pulse duration of 492 fs.
· The reliability of the mode-locked fiber laser was validated by its continuous operation, highlighting its suitability for highly stable optoelectronic applications. Additionally, a Q-switched EDZFL with a central wavelength of 2801.87 nm, an SNR of 46.8 dB, and a pulse duration of 766 ns has also been demonstrated.
