Orthogonal Dual-Frequency SOA-Fiber Laser
Keyword(s):
In order to develop a new orthogonal dual-frequency laser, we studied a fiber ring laser using a SOA (semiconductor optical amplifier) and aim to apply it to a novel light source for optical heterodyne interferometry. The frequency difference was generated by a linear or circular birefringent medium inserted into the ring cavity. To obtain heterodyne signal optical and electrical filters were introduced.
