TUNABLE LASER DIODE DEVICE WITH AMZI-FP FILTER

摘要

The tunable light source structure proposed in the present invention has an advantage in that a limitation on a typical technology not simultaneously satisfying high-speed tuning and wide range tuning is overcome and thus it is possible to simultaneously satisfy high-speed tuning slower than or equal to several ns and 100 nm-level wide range tuning. Also, a driving method is simpler than that of a typical technology, a stable operation is possible, and it is possible to lower a manufacturing cost of all modules including a driving circuit. In implementing the SLD and the AMZI-FP that are key components of the tunable light source structure of the present invention, an Si or polymer optical waveguide as well as III-group to V-group materials (GaAs, InP and GaSb) may also be employed.
