HIGHLIGHTS
- who: Shai Gertler from the Yale University have published the research work: Narrowband microwave-photonic notch filters using Brillouin-based signal transduction in silicon, in the Journal: NATURE COMMUNICATIONS NATURE COMMUNICATIONS
- what: The authors show that many of these issues can be addressed by using a new signal processing scheme that utilizes Brillouin interactions within a multi-port photonic-phononic emitter-receiver (PPER) device25. The authors show how the notch 2 frequency can be shifted over multiple GHz by using an optical local oscillator at the filter input, without degrading the narrowband (~MHz) filter resolution . . .
