Abstract

We present a complete analysis of the operation of an ultra-fast tunable parallel optical delay line. Based on our analysis, we propose and experimentally demonstrate a generalized serial–parallel delay line structure, which provides better scalability with respect to the number of timeslots. The delay line uses one electro-optic modulator and an all-fiber delay lattice. We also present a discussion on two important performance measures of this delay line – the tuning speed and the optical power loss.
