Abstract

In this paper, we demonstrate an 8-bit silicon optical true-time delay line with a high resolution of 1.78 ps based on the cascaded optical switches. The total delay time is larger than 400 ps. The crosstalk of the optical switch is below -25 dB and -21 dB in the C band under cross-state and bar-state, respectively. The calculated delay loss is about 2.4 dB/ns.
