摘要：

In this letter, we describe a technique for high frequency (up to 100 GHz), narrow-band (approximately GHz) optical modulation by encoding the millimeter wave signal onto a beat note, produced by photomixing of two 1.3 mum DFB lasers. The phase noise on the beat note is compensated by a feedforward technique, using a low frequency external optical modulator, which simutaneously encodes the information to be transmitted. The modulation band can be tuned by varying the lasing frequency of one or both of the lasers. We investigated the fundamental performance limit of this technique and demonstrated transmission of a pulsed RF signal at 40 GHz.
