摘要:
In this letter, we propose and experimentally demonstrate the possibility of obtaining low-cost reconfigurable RF filters based on the combined use of multimode Fabry-Perot (FP) lasers and optical dispersive elements. The key to attain reconfigurability is the modification of the FP laser optical spectrum by means of changing the bias injection current to the device.
