Abstract

In order to implement negative coefficients filters based on photonics in optical communication,a novel and simple technique for obtaining negative coefficients was adopted by means of the conversion of phase-modulated to intensity-modulated.A two-tap microwave band-pass filter with a negative coefficient was demonstrated.The filter not only achieves the negative coefficients but also improves the performance.
- optical communication,
- negative coefficients,
- photonics,
- phase-modulation to intensity-modulation,
- tap
