Lab in a fiber
Lab-in-a-Fiber (LIF) is a conceptual device development paradigm that operates within the optical geometry of microstructured optical fibers. It enables the creation of functional, robust sensing and actuating devices, with significant potential for deployment across diverse vertical and horizontal markets, including healthcare, food quality, energy, safety and security, and environmental monitoring.
Optical Fibers for Second Harmonic Generation
Our recent work exemplifies the lab in a fiber paradigm by demonstrating electrically poled, hybrid microstructured optical fibers capable of efficient in-fiber second harmonic generation (SHG). The fiber is infused with 2-methyl, 4-nitroaniline (MNA) and enhanced via electric field poling. This process significantly boosts second harmonic generation and transmission performance by improving material crystallinity. Advanced microscopy and imaging reveal how the poling reshapes light guidance in the fiber. The results show how material engineering inside the fiber microstructure enables controllable nonlinear wavelength conversion—an essential building block for fully integrated fiber-based photonic systems. The work paves the way for next-generation in-fiber light switching and
wavelength conversion devices.
