Nondestructive 3-D imaging of femtosecond laser written volumetric structures using optical coherence microscopy
نویسندگان
چکیده
Nondestructive three-dimensional imaging of femtosecond laser-written buried structures is demonstrated using optical coherence microscopy providing lateral and depth resolution on a micron scale. This high speed technique, which requires no sample preparation, enables the visualization of volumetric structural modification created deep in transparent dielectric medium with high signal/noise contrast. Images of buried void structures with dimensions as large as 190 μm in length were obtained without shadowing effects impugning the image fidelity.

Three-dimensional imaging of direct-written photonic structures.
Third-harmonic generation microscopy has been used to analyze the morphology of photonic structures created using the femtosecond laser direct-write technique. Three-dimensional waveguide arrays and waveguide-Bragg gratings written in fused-silica and doped phosphate glass were investigated. A sensorless adaptive-optical system was used to correct the optical aberrations occurring in the sample...
متن کاملPolarized Third-harmonic Generation Imaging of Two-photon Photopolymerized Microstructures
Two-photon photopolymerization (TPP) has been shown to be a versatile tool for fabricating subwavelength features that are localized in three dimensions (3D) [1]. However, detection of the photopolymerized structures after polymerization is difficult as the polymerized regions exhibit poor contrast against the background when viewed under a conventional light microscope. Furthermore, the tradit...
