A new chip-sized microwave photonic filter has been developed by scientists to detach communication signals from noise and curb undesirable interference happening throughout the complete radio frequency spectrum.

Just as light have different polarization when propagating in free space, there are similar properties in integrated optical waveguides, we call it 'TE' polarization and 'TM' polarization.
