✦ Synopsis

Abstract

A novel tunable coherence‐free microwave photonic filter configuration is presented. This all‐optical structure realizes negative taps and works as a bandpass notch filter. The configuration is based on a Sagnac loop interferometer containing a single‐drive intensity modulator and a polarization‐maintaining semiconductor optical amplifier that generates phase difference between the clockwise and counterclockwise propagating waves inside the Sagnac loop. Measured results demonstrate a robust tunable bandpass notch response. © 2007 Wiley Periodicals, Inc.

A simple design of multi-wavelength generation in the S-band region of the optical network transmission is proposed. The design consists of broad-band fiber Bragg grating (BB-FBG), which acts as a filter to enhance operation in the S-band region. A Sagnac loop mirror (SLM) is used to generate multip
