/ Optical Characterization of Perovskite-Based Lasers with Photonic Crystal Resonators
Optical Characterization of Perovskite-Based Lasers with Photonic Crystal Resonators
Explore how nanostructured photonic crystals control light emission in perovskite lasers, paving the way toward integrated and electrically driven light sources.
This internship focuses on the experimental optical characterization of perovskite-based lasers integrated with photonic crystal resonators , including two-dimensional (2D) lattice designs . These periodic dielectric structures enable strong light -matter interaction, mode confinement, and tailored dispersion properties, making them ideal platforms for next-generation laser devices.
The project will involve systematic characterization of key laser performance metrics, such as:
Lasing threshold and efficiency under controlled excitation conditions.
Spectral properties including emission wavelength, linewidth, and mode spacing.
Angular and polarization dependence of emission to probe photonic band structure effects.
To achieve these objectives , the intern will work with a state-of-the-art optical setup equipped with high-resolution spectrometers, imaging systems, and precision alignment tools. Advanced techniques such as Fourier-space imaging will be employed to map dispersion relations and identify resonant modes within the photonic crystal lattice.
Beyond data acquisition, the project will include interpretation of experimental results in the context of photonic crystal theory and perovskite material properties , providing insights into how structural design influences lasing dynamics. These findings will guide optimization strategies for perovskite laser devices with tailored emission characteristics for integrated photonic applications.
This internship offers a unique opportunity to gain hands‑on experience in cutting‑edge optical characterization methods, photonic device physics, and experimental data analysis, contributing to the development of novel light sources for emerging technologies.
Key skills:
Background in photonics or physics
Fundamental knowledge of optics and photonics, including laser physics and resonator theory.
Optional but beneficial: Simulation tools (FDTD, COMSOL, or similar) for photonic structures.
The reference code for this position is 2026-INT-212. Mention this reference code in your application.
Imec allowance will be provided.
