A new architecture of photonic link with balanced receivers is introduced. The newly proposed architecture can reduce
both the influence of the relative intensity noise (RIN) of LD and the even order distortion of the optical modulator.
Results show that 21dB RIN suppression is obtained.
Time Delay Resolution (TDR) of Optical Beam Forming Network (OBFN), is discussed with theoretical calculation and numerical analysis. Time delay ripples apart from ideal time delay exist in single optical true time delay link and delay array based OBFN, but counteract between WDM links. Thus, OBFN is recommended to use WDM architecture.
