Abstract
Disclosed herein is a notch filter and a method for generating an electrical signal with a suppressed frequency band. The filter generates an optical signal by modulating a modulation optical wave with an electrical signal to generate first and second sidebands. The first sideband or the second sideband has less power than the other. The filter then modifies the optical signal by equalizing the power of light within the first side band at a selected frequency band and light within the second side band at the selected frequency band. The filter then produces an antiphase relationship between the light within the first side band at the selected frequency band and the light within the second side band at the selected frequency band. The filter then detects the modified optical signal to generate a copy of the electrical signal with suppressed frequency components within the selected frequency band.
