Latest Patents

Sven Bader holds a patent for a vertical cavity surface emitting laser. This VCSEL features first and second electrical contacts, along with an optical resonator. The optical resonator includes first and second distributed Bragg reflectors (DBRs), an active layer, and a distributed heterojunction bipolar phototransistor (DHBP). The DHBP is composed of a collector layer, light-sensitive layer, base layer, and emitter layer. An optical coupling exists between the active layer and the DHBP, providing active carrier confinement. The optical guide, which is outside the current flow provided by the electrical contacts, guides an optical mode within the optical resonator during operation. This innovative design allows for improved functionality and efficiency in laser applications.
