In this presentation, we propose and experimentally demonstrate a novel optical generation of microwave and
millimeter wave signals by using asymmetric fiber Bragg grating Fabry-Perot cavity fiber laser, dual-wavelength
emission can be achieved with wavelength separation of 0.68nm corresponding to the millimeter wave signal at
85GHz. By appropriately adjusting the operation temperature of intracavity fiber Bragg grating, the frequency of
millimeter wave signal generated can be tunable. Our experimental results demonstrate the new concept of optical
generation of microwave and millimeter wave signals by using asymmetric fiber Bragg grating Fabry-Perot cavity
dual-wavelength fiber laser and the technical feasibility.
In this paper, a ring cavity passively mode-locked fiber laser using a semiconductor saturable absorber mirror as
saturable absorber and a fiber Bragg grating as dispersion compensator, is proposed and experimentally demonstrated,
its output performance is discussed. Stable mode-locking spectrum with 3dB bandwidth of 3.2nm, center wavelength
of 1555.8nm and average output power of 0.32mW is observed at the pump power of 110mW. The pulse repetition
rate is 25 MHz, as determined by the cavity length of ~8m in case of the output sech2 transform-limited pulse, the
output pulses duration of 0.79ps and single pulse energy of 12.64pJ are obtained.
