Tunable and reconfigurable multiwavelength fiber optical parametric oscillator with 25 GHz spacing.
We demonstrate a multiwavelength fiber optical parametric oscillator based on a nonlinear fiber as the gain medium. Using a transmission grating filter cascaded with a programmable filter as wavelength-selective elements, we achieve multiwavelength operation with 129 lasing wavelengths spaced apart by 25GHz. The power nonuniformity is less than 4.5dB with a power fluctuation of less than 0.1dB over a 20min period. Moreover, we realize tunable and reconfigurable functions over the entire lasing spectrum (approximately 25.6 nm), which greatly enhances the performance and flexibility of this laser.
