Latest Patents

One of Dufour's latest patents is titled "Method of and device for pulse-mode driving a semi-conductor laser." This invention describes a method and device that operate a semiconductor laser by initially driving it into the LED region with a pedestal current pulse. This is achieved using a first current source, followed by the superposition of an information current pulse from a second current source after current stabilization. This two-stage drive reduces switching transients, allowing for shorter pulses and minimizing unnecessary power dissipation, which ultimately extends the lifetime of the semiconductor laser.

Another significant patent by Dufour is for an "Optical recording element." This invention consists of an assembly of two parallel substrate plates made from transparent synthetic resin. Each plate features a recording layer on its facing sides, which includes a guide track in the form of a spiral-like groove. Additionally, a foil of synthetic resin engages the ridges of the recording layers present between the groove turns, enhancing the optical recording capabilities.
