Latest Patents

John Walsh holds a patent for an "Automated Laser Diode Test System." This invention discloses a comprehensive testing and burn-in system for laser diodes. The system begins by obtaining initial device data through current application at room temperature, followed by a burn-in process at elevated temperatures. Throughout this process, device performance is meticulously monitored. After cooling, the post burn-in power is measured again under identical test conditions. If any device parameters deviate beyond a specified threshold, the device is rejected. Conversely, if the parameters remain stable, the device is accepted for further assembly. This test system offers significant advantages over previous methods by integrating an easy-to-load laser test fixture, automatic device hold-down features, heating capabilities, and a computer-driven test protocol. This protocol performs initial measurements, calibrates laser and photodetector pairs, conducts burn-in tests, and stores laser test history records, all while enabling remote access to these records. The invention effectively reduces labor-intensive steps and the need for costly test fixtures.
