Freely controllable single-optical-frequency comb for highly sensitive cavity ring-down spectroscopy [PDF]

Scientific Reports
Direct comb spectroscopy is a powerful tool for obtaining highly accurate spectroscopic information. However, because the number of comb modes is extremely large, the optical energy is distributed over many modes, resulting in ultrasmall optical power ...

Nonlinear Absorbing-Loop Mirror Mode-Locked all-Polarization-Maintaining Yb-Doped Fiber Laser

IEEE Photonics Journal, 2021
In this paper, a nonlinear absorbing-loop mirror (NAbLM) is constructed in a polarization-maintaining (PM) version and applied in the all-normal dispersion (ANDi) regime, for the first time to our best knowledge. To investigate the properties of NAbLM in

Bound-State Soliton and Noise-like Pulse Generation in a Thulium-Doped Fiber Laser Based on a Nonlinear Optical Loop Mirror

Applied Sciences, 2022
We demonstrate a thulium-doped, mode-locked, all-fiber laser capable of operating in two generation regimes: dispersion-managed soliton and noise-like pulse (NLP).

Interval-Adjustable Multi-Wavelength Erbium-Doped Fiber Laser With the assistance of NOLM or NALM

IEEE Access, 2021
A novel interval-adjustable multi-wavelength erbium-doped fiber laser (EDFL) is experimentally demonstrated in this paper. The proposed EDFL is based on the cascaded structure of two-segment Sagnac filter and nonlinear optical loop mirror (NOLM).

Bandpass switching in a nonlinear-optical loop mirror [PDF]

Optics Letters, 1995
A novel device configuration is used to demonstrate wavelength-confined, a bandpass, switching in a nonlinear-optical loop mirror (WOLM). Demonstrated is a self-switching in the soliton regime using a partially reflecting Bragg grating as a wavelength-dependent loss element.

Soliton switching using cascaded nonlinear optical loop mirrors [PDF]

Conference on Lasers and Electro-Optics Europe, 1994
Ultrafast soliton switching using the nonlinear optical loop mirror (NOLM) has been demonstrated both theoretically and experimentally.1,2 In addition, it has been shown that device cascading leads to an overall sharpening of the switching char acteristic.3-5 To date, however, the effects of cascading NOLMs operating in the soliton regime have not been
