AI Article Synopsis
- A new wavelength-tunable all-fiber mode-locked erbium-doped fiber laser has been created using a supermode interference filter (SMIF) made from a seven-core fiber connected to standard single-mode fibers.
- By exciting two supermodes in the fiber, the SMIF produces a broad comb-shaped transmission spectrum, allowing for variable wavelength output.
- The laser emits 230 fs pulses with a spectral width of 14 nm and can tune its output spectrum within a range of 22 nm while maintaining stable mode-locking operation.
Article Abstract
A wavelength-tunable all-fiber mode-locked erbium-doped fiber laser has been proposed and realized by using a supermode interference filter (SMIF). The SMIF is fabricated by splicing a segment of seven-core fiber (SCF) to two standard single-mode fibers. Since two supermodes of the propagating light are excited in the SCF, the transmission spectrum of the SMIF shows a clean broadband comb-shape characteristic. By bending the SMIF in the proposed mode-locked laser, the output spectrum can be continuously tuned in a wavelength range up to 22 nm while keeping mode-locking operation. The self-starting laser produces 230 fs pulses with a spectral width of 14 nm.

We present for the first time, to the best of our knowledge, the pump-power-controlled, all-polarization-maintaining (all-PM), all-fiber configured, wavelength-tunable mode-locked fiber laser in the L-band (1565 to 1625 nm). A tuning range over 20 nm (1568.2 to 1588.

The master oscillator is a Tm fiber ring laser incorporating a tunable bandpass filter to realize narrow linewidth and wavelength tunable operation. The MOPA generated 1010 W ∼1039 W of output power over a tuning range of 107 nm from 1943 to 2050nm with slope efficiencies of more than 51% and spectra linewidth of ∼0.

This filter is implemented in an all-PM mode-locked fiber laser to serve as a novel wavelength-tuning mechanism for fast wavelength sweeping. The center wavelength of the output laser can be tuned across a range from 1540 nm to 1567 nm linearly.

The wavelength, pulse duration and spectral bandwidth of passive mode-locked lasers can be tuned by controlling the polarization controller. The proposed Lyot filter was constructed by a single-mode fiber insertion between two polarization-maintaining fibers.

The 1-order and 3-order OAM modes are excited based on the HLPFGs inscribed in the single-mode fiber (SMF) and six-mode fiber (6MF), respectively. Theoretical analysis reveals that the twisting can result a resonant wavelength shift of the HLPFG, which means that the OAM modes can also be excited at various wavelength by simply applying a twist rate on the HLPFG.
