The patent US-10,561,628 addresses a semiconductor micro device comprising of at least one cavity and one multilayer interference reflector. The device represents a micrometer-scale pillar with an arbitrary shape of the cross section and enables operation at low resistance and ultra-low capacitance. The technology can be applied to vertical cavity surface emitting lasers (VCSEL) and VCSEL arrays to further advance the modulation speed for short reach optical data communication at very high data rates.  

VCSEL chips are low-cost, energy efficient devices, which provide high-performance in a wide range of applications from data communication to 3D sensing. The patented micropillar structure significantly improves the performance and reliability in consumer and industrial applications.  

The grant of the patent provides further recognition of the quality of the innovation being carried out by VI Systems’ team.
