Journal of biomedical optics, 2008•spiedigitallibrary.orgWe developed a technique for constructing light diffusing devices comprised of a flexible
shape memory polymer (SMP) cylindrical diffuser attached to the tip of an optical fiber. The
devices are fabricated by casting an SMP rod over the cleaved tip of an optical fiber and
media blasting the SMP rod to create a light diffusing surface. The axial and polar emission
profiles and circumferential (azimuthal) uniformity are characterized for various blasting
pressures, nozzle-to-sample distances, and nozzle translation speeds. The diffusers are …

We developed a technique for constructing light diffusing devices comprised of a flexible shape memory polymer (SMP) cylindrical diffuser attached to the tip of an optical fiber. The devices are fabricated by casting an SMP rod over the cleaved tip of an optical fiber and media blasting the SMP rod to create a light diffusing surface. The axial and polar emission profiles and circumferential (azimuthal) uniformity are characterized for various blasting pressures, nozzle-to-sample distances, and nozzle translation speeds. The diffusers are generally strongly forward-directed and consistently withstand over of incident IR laser light without suffering damage when immersed in water. These devices are suitable for various endoluminal and interstitial biomedical applications.
