A novel structure of double-ring slow-light gyroscope with two input–output waveguides is studied. We utilize interferometric detection method, and sufficiently combine the advantages of Interferometric Fiber Optic Gyro (I-FOG) and Resonator Optic Gyro (ROG). The responses of the structure are derived and simulated. Here two experimental schemes are also proposed. By applying a square wave to the...
A simple single-longitudinal-mode (SLM) dual-wavelength erbium-doped fiber ring laser is proposed and demonstrated at first by using an arrayed waveguide grating (AWG) as wavelength filter. Owing to the two sub-ring cavities with different cavity losses, equalized dual-wavelength output can be achieved easily utilizing cavity loss control. The SLM operation is guaranteed by self-injection feedback...
