VI Systems, a provider of ultra-high speed components for data communications, has acquired an exclusive license to the US patent 8,472,496 – Optoelectronic Device and Method of Making Same – for applications in optical data communications, sensing, and illumination using vertical cavity light–emitting diode structures.

The patent addresses the possibility of fabrication of surface–emitting lasers and light–emitting diodes in any materials system by attaching a dielectric cavity layer, confined by multilayer dielectric distributed Bragg reflectors (DBRs) on both sides of the gain medium.

The concept enables the trapping and amplification of light, even the cavity layer itself remains passive. This approach eliminates the need in lattice–matched high conductivity all–semiconductor DBRs and allows easy integration of the device to photonic crystals, subwavelength gratings, waveguides, offers an option of high temperature stability of the wavelengths for uncooled DWDM applications and provides multiple further advantages.
