Summary: Photonic frequency converters are optical systems used to translate data at RF or microwave frequencies to new carrier frequencies for processing or retransmission. The performance of these converters is governed by complex nonlinear functions that require detailed simulations to assess the impact of various architectures and components. This work provides analytic expressions for the primary metrics of photonic frequency converters, validated through comparison with simulations and experiment.

Summary: Photoelectric conversion is an essential process for devices such as solar cells, and great advances have been made in utilizing metamaterials for PC devices from microwave to optical range. The absorption mechanism varies with the waveband, with electromagnetic polariton resonance dominating in the microwave and surface plasmon resonance in the optical band. Terahertz photoelectric devices exhibit unique characteristics different from electronics and optics, dependent on the frequency.
