Photonic lanterns (PL) and mode-selective photonic lanterns (MSPLs) are fiber-based devices that facilitate bidirectional light transfer between multimode and single-mode waveguides. Diverse applications of PLs include fields such as astrophysics, telecommunications, and biophotonics. Characterized by near-lossless performance, wide operational bandwidth, and high modal isolation, PLs face challenges like single-mode compatibility and scalability, which can be resolved using double-clad or graded-index fibers. This study investigates the characteristics of various 3-mode PLs fabricated from double-clad fibers. Using a dedicated setup, we analyze how these PLs respond to different wavelengths and polarization states. Results indicate that standard PLs exhibit significant optical profile variability based on illumination conditions, while MSPLs maintain stable optical properties across these variations.
