Title: The Innovations of Petter Westbergh
Introduction
Petter Westbergh is an accomplished inventor based in McKinney, TX (US). He has made significant contributions to the field of optical technology, particularly in the development of vertical cavity surface emitting lasers (VCSELs). His innovative work has led to the granting of a patent that showcases his expertise and creativity.
Latest Patents
Westbergh holds a patent for a "Feedback biased vertical cavity surface emitting laser." This invention includes a bottom distributed Bragg reflector (DBR) mirror and a top DBR mirror positioned above the bottom mirror. The VCSEL features a vertical optical cavity designed to emit an optical signal. Additionally, it incorporates a lateral feedback optical cavity that receives a feedback bias signal, allowing for adjustments to the emitted optical signal. The active region of the VCSEL is formed between the two DBR mirrors and includes an oxide layer that defines an oxide aperture. Furthermore, an isolation implant is utilized to electrically isolate the vertical optical cavity from the feedback optical cavity, creating distinct apertures within the oxide aperture.
