Abstract
In this thesis, we first use adaptive freezing phase algorithm to produce a reference transform-limited pulse. The light source is 1550nm mode-locked Er:fiber laser. In addition, we also demonstrated an arbitrary waveform generation by adaptive Gerchberg-Saxton algorithm. Besides, we also applied spectral shaping technique in high speed optical communication. By combining optical comb generated by phase modulation of continuous wave, programmable shaper and photonics W-band fiber-wireless system, we proposed an easily upgradable and service-integrated access network. The users can easily upgrade their system by changing optical band-pass filter. The wired data rate and wireless data rate can achieve 17.45 Gb/s and 3.36Gb/s respectively after 40 km of single-mode fiber. The radio frequency power fading effect in the fiber also investigated in this experiment.
