Light extracting device and light extracting method
A light extracting device includes a dual light generating unit and a first order Bragg grating unit. The dual light generating unit is for receiving an input optical signal and a control signal, and for generating from the input optical signal first and second optical signals that have a phase difference there between. The phase difference is associated with the control signal. The first order Bragg grating unit is for receiving the first and second optical signals from the dual light generating unit, and for causing optical interference to occur between the first and second optical signals within a predetermined wavelength range to result in first and second output optical signals.
