Interferometric tunable optical filter |
摘要 |
An interferometric tunable optical filter selects a predetermined wavelength or wavelengths from a wavelength division multiplexed signal. The optical filter splits an input signal into a plurality of waveguide branches. In each branch, the amplitude and phase of the signal can be individually controlled. The signals are then recombined. The resulting interference gives a wavelength dependent transmission spectrum that can be adjusted as desired.
