摘要：
A new wideband linearised photonic mixer structure based on a parallel topology of two electrooptic modulators is presented. This mixer realises a high spurious free-dynamic range (SFDR), with additional advantages of requiring only a small amount of optical power and operating over a multioctave range. Experimental results for the linearised photonic mixer demonstrate a measured receiver-noise limited SFDR of 115 dB (.) Hz(4/5) with a low input optical-power requirement of only 5 mW. This offers multi-octave high dynamic range optical frequency conversion with wideband operation. (C) 2003 Wiley Periodicals, Inc.
