Latest Patents

Chiachi Wang holds a patent for an "Optical amplifier with power dependent feedback." This invention features an optical feedback resonant laser cavity (OFRC) that includes a power dependent loss element (PDLE). The PDLE is designed such that as the incident laser power on the PDLE increases, the cavity loss decreases. This configuration allows for improved optical gain control or optical power control in WDM amplifiers or single channel power equalization amplifiers (PEA). Additionally, the patent describes a 1×N×N WADM node that incorporates multiple amplifiers, some of which share a common pump source. The invention also outlines methods for managing transient power changes in single channel optical amplifiers and reducing DC gain errors in WDM optical amplifiers under dynamically variable operating conditions.
