Abstract

We propose and experimentally demonstrate a chirp-free carrier-suppressed optical pulse generator using a simple and cost-effective approach. An 80-GHz carrier-suppressed optical pulse train was successfully obtained by using two cascaded 20-GHz clock-driven dual-drive Mach-Zehnder modulators. Compared with the conventional scheme using 40-GHz clock driving signal to generate an 80-GHz pulse train, the proposed scheme is cost-effective and scalable to high repetition rate pulse generation by using low-speed devices.
