Abstract:

We propose a novel phase shift keying technique that uses optical delay modulation for fiber-optic radio links. Using only a 2 × 1 switch and a delay line, this technique enables modulation of a millimeter-wave carrier at bit rates of several gigabits per second or higher, where high-speed devices are not needed. Binary phase shift keying (2PSK) was experimentally demonstrated. 2-Gb/s data signal on a 40-GHz carrier was transmitted over a 5-km optical fiber without any error. The coherent crosstalk noise, due to insufficient extinction ratio of optical switches,was evaluated. The 2PSK modulation technique can be extended to multi-phase shift-keying modulation.
