AZO Nanotechnology -- Researchers of the Max Born Institute for Nonlinear Optics and Short-Pulse Spectroscopy (MBI) have developed a novel optical fiber that enables transmission of ultrashort light pulses with an unprecedented low degree of distortions. The researchers transmitted light pulses of 13 fs duration (1 fs = 1 millionth billionth of a second) over one meter distance, with the pulses only stretching to about double of the initial duration. "Currently, no other fiber-based technique is capable of such little distortion", says Dr. Günter Steinmeyer. In comparison, using similar fibers of a more conventional make, pulse stretching to more than 50 times the original duration was observed. The novel fibers may be useful in medical applications, e.g., for . In their advance online section, Nature Photonics reports about this novel type of fiber.
