Title: Walter Margulis: Innovator in Optical Fiber Technology
Introduction
Walter Margulis is a notable inventor based in Huddinge, Sweden. He has made significant contributions to the field of optical fiber technology, holding a total of five patents. His innovative methods have advanced the capabilities of fiber optics, particularly in applications such as laser technology.
Latest Patents
One of Margulis's latest patents is a method for changing the refractive index of an optical fiber by applying a high voltage pulse to a longitudinal electrode. This method involves temporarily altering the refractive index of the fiber by applying a high voltage pulse of at least 100 volts. The pulse is designed to be of a duration short enough to prevent melting of the electrode, allowing for thermal expansion through ohmic heating. This technique is particularly useful for Q-switching in fiber lasers. Another significant patent is a method for forming a longitudinal solid body within an optical fiber. This process includes placing a portion of the optical fiber in a heating chamber and forcing molten material into a longitudinal hole in the fiber. The controlled extraction of the fiber while urging molten material into it is a key aspect of this innovative method.
