AI Article Synopsis
- The text discusses how optical filters cause delays in microwave phase shifting systems that use slow-light technology.
- It explains the calculation of filter delay through the Kramers-Kronig relations, based on the measured amplitude response.
- The findings are integrated into a numerical model to clarify experimental phase shifting results, employing semiconductor optical amplifiers as the slow light components.
Article Abstract
We highlight the importance of the delay arising from optical filters in slow-light-based microwave phase shifting systems. We calculate the filter delay numerically from the measured amplitude response by using the well-known Kramers-Kronig relations. The complex filter transmission response is then incorporated within a numerical model with which we explain phase shifting results obtained from experiments employing semiconductor optical amplifiers as slow light elements.
