Optical heterodyne detection - Wikipedia

WebAbstract: In gravitational wave interferometric detection, the problem of stray light has received long-term attention. In the spaceborne gravitational wave detection program, the laser light emitted by the local interferometer produces backward coherent stray light when passing the telescope while the radiation from space that is incident to the spacecraft … WebThe authors first show how the combination of advanced modulation techniques, DSP and coherent detection has led to significant gains in capacity and ease of operation. The authors follow the path of the information from its generation in the transmitter, to propagation through the fiber and processing by the DSP algorithms in the receiver. WebJan 22, 2024 · As a demonstration, we consider a photonic crystal slab structure and show that differentiation operation with incoherent light can be achieved by subtracting the optical transfer function of the structure at two different frequencies. someone on bath salts
