High power MEMs-tunable vertical-cavity surface-emitting lasers

The technology is based on a micro-electromechanical vertical-cavity tunable laser that is optically pumped by a co-packaged 1310 nm pump source and controlled by a co-packaged broadband wavelength locker and power monitor. A schematic of the MEM-VCSEL device discussed in this work. The spot size of the fundamental lasing mode is measured to be -10 μm Single-mode operation is obtained for all pump powers across the tuning range.
