Abstract :
A novel and simple optical single sideband with carrier (SSB+C) modulation scheme implemented using an ultranarrow dual-transmission-band superstructured equivalent phase shift (EPS) fiber Bragg grating (FBG) is presented. The FBG with two ultranarrow transmission bands is created by introducing two EPSs in its structure during the fabrication process. The use of EPSs instead of true phase shifts allows the reduction of the stringent requirement for accurate phase shifts during the fabrication process. An experimental setup using the EPS FBG to implement SSB+C modulation is demonstrated. The performance of the SSB filter is studied by analyzing the eye diagrams and bit-error-rate measurements
