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.

A fiber ring-cavity laser based on InP/InGaAsP multi-quantum wells semiconductor optical amplifier is proposed and experimentally demonstrated. The laser uses InP/InGaAsP multi-quantum as well as the gain medium and fiber Bragg grating as the wavelength selector. It’s demonstrated that the center wavelength of the output amplified spontaneous emission spectrum for the InP/InGaAsP multiple-quantum wells appears blue shift when its injection current increases. A lasing at central wavelength of 1549.66 nm with the maximum output power of 1.524 mW is obtained with electro-optical efficiency of 1.1% at injection current of 220 mA and the fiber Bragg grating operating temperature of 23[Formula: see text]C. The threshold injection current of the laser is 78 mA. When the operating temperature of fiber Bragg grating increases from 8[Formula: see text]C to 28[Formula: see text]C, the center wavelength of output laser increases from 1549.27 to 1549.59 nm. It shows that the laser has good temperature stability.
