- A novel single-longitudinal-mode (SLM) erbium-doped fiber laser with a simple linear cavity based on a fiber Bragg grating Fabry-Perot filter (FBG-FPF) and a narrowband (similar to 0.06 nm) FBG is proposed and demonstrated experimentally. Two uniform FBGs form the FBG-FPF, which has two ultranarrow transmission bands with a bandwidth of 0.12 pm and a wavelength spacing of 0.095 nm. By slightly tuning the central wavelength of the narrowband FBG, SLM lasing at 1549.658 or 1549.563 nm (corresponding to the two transmission peaks of the FBG-FPF) is achieved with a laser output power of similar to 4 mW, when the pump power is similar to 75 mW.

Journal article (peer-reviewed)abstract
- A novel method of microwave frequency up/downconversion is proposed for microwave/millimetre-wave-based radio-over-fibre (RoF) systems. The uplink and downlink are both based on dual-wavelength single-longitudinal-mode fibre laser modulation and heterodyning, which provides the possibility to realise bidirectional RoF transmissions.
