Title: The Innovations of Slimane Loualiche
Introduction
Slimane Loualiche is a notable inventor based in Lannion, France. He has made significant contributions to the field of optical technologies, holding a total of 5 patents. His work has been influential in advancing optical packet switching systems and laser technologies.
Latest Patents
One of Loualiche's latest patents is an optical packet switching system. This innovative system identifies the routing of each optical packet and directs each packet arriving at any input to the corresponding output. It includes delay lines through which the optical signals pass selectively. The switch operates in three stages: the first stage directs each optical packet received at an input to a chosen delay line, the second stage couples to the output of the delay lines to direct the optical packets selectively to the output corresponding to the determined routing, and the third stage serves as the output. Another significant patent is for a vertical cavity laser of low resistivity. This laser structure comprises an active region between stacks of layers forming Bragg reflection mirrors of both n-type and p-type. The n-type mirror consists of materials with a narrow or non-existent conduction band gap, while the p-type mirror comprises materials with a narrow or non-existent valence band gap.
