Single-polarization generation in fiber Fabry-Perot laser by self-injection locking in short feedback cavity

Single-frequency and single-polarization lasing can be generated in a compa ct self-injection locked fiber Fabry-Perot laser with a short fiber Bragg g rating feedback cavity, No discrete polarization control components are req uired. Different wavelengths across the laser gain bandwidth can be generat ed by an appropriate combination of cavity designs and feedback fiber Bragg gratings,A 10-Gb/s: nonreturn-to-zero transmission test demonstrates the l aser's applicability for optical fiber communications.
