Switchable multiwavelength erbium-doped fiber ring laser with a multisection high-birefringence fiber loop mirror

Wavelength spacing tenable capability of optical comb filter using Polarization Maintaining Fiber

“…The birefringent comb filter plays a significant role in the processing of microwave and optical signal. Because of the increasing application in multi wavelength fiber lasers [1], it has attracted much attention in recent years [2]. It is desirable for a comb filter to be tunable in spectral spacing.…”

Fiber Loop Mirror Filter With Two-Stage High Birefringence Fibers

“…Fiber loop mirrors (FLMs) have been intensively developed and commonly used for many applications such as in all-optical signal processing and multi-wavelength fiber lasers [1][2][3]. This is attributed to their advantages such as low cost, low loss, simple construction and polarization independence [4,5].…”

Switchable and tunable Erbium-doped fiber ring laser incorporating a birefringent and highly nonlinear photonic crystal fiber

“…Based on the self-stabilizing effect of the four-wave mixing (FWM), the application of a highly nonlinear PCF successfully suppresses the mode competition in Erbiumdoped fiber laser at room temperature. Moreover, switchable and tunable fiber lasers have been widely investigated recently due to their important applications in wavelength division multiplexing (WDM) systems, fiber sensors, spectroscopy and optical instrument testing [7][8][9][10][11]. Among them, EDFLs have been widely investigated due to their advantages such as the high power conversion efficiency and lower threshold [8][9][10][11].…”
