摘要：
We report a cold-start, 1.7 Gb/s FSK heterodyne single-filter detection system using ordinary single-electrode DFB lasers. These lasers were frequency-locked to an atomic Krypton line at 1.5224 “m independently. Thus, this system can maintain a constant IF without an IF locking circuit and consequently does not require any IF acquisition circuitry for cold-start operation. The measured receiver sensitivity of this system was −41 dB (1 mW) at an error rate of 10−9. © 1990 IEEE
