RF power sensor linearity is a commonly misunderstood topic. To obtain the most accurate power measurements, though, you need to understand what linearity is, the sources of nonlinearity, and how to ...

The ?ourishing of topological photonics in the last decade was achieved mainly due to developments in linear topological photonic structures. However, when nonlinearity is introduced, many intriguing ...

The circuit in Figure 1 converts the input DC voltage into a pulse train. The period of the pulses is proportional to the input voltage with a 50% duty cycle and a ...

(a-b) Reconstructed image of absorption coefficient at (a) low and (b) high light fluence. The entire optoacoustic data (c) was generated using a modified model-based reconstruction algorithm designed ...
