Latest Patents

Roxlo's latest patents include an article comprising a semiconductor laser with a stable facet coating. This innovation allows for high reliability in semiconductor lasers without the need for hermetic enclosures. These lasers are particularly useful in optical fiber telecommunications and compact disc players. The non-hermetic lasers feature facet coatings made from a dielectric layer with a very low water saturation value, specifically SiO.sub.x, which is deposited using a molecular beam method. The deposition conditions are meticulously chosen to ensure a dense material that is largely free of particulates and blisters, making it substantially impermeable to moisture.

Another significant patent involves a method of producing a semiconductor laser adapted for use in analog optical fiber communication systems, such as CATV systems. This method simplifies the process of identifying suitable lasers by using readily determinable parameters to predict intermodulation behavior. By measuring the light versus current characteristics of a laser, Roxlo's method allows for a more economical approach to laser fabrication.
