[求助] 小弟求助一道Microwave Photonics的题,急!~谢谢大家

The light from two semiconductor lasers is coupled into an optical fiber and detected with a photo-detector.  The detector is connected to an RF spectrum analyzer (RFSA).  The wavelengths of the two lasers are 1550.1 nm and 1555.0 nm, each laser having a linewidth of 100 MHz.  What will be observed on the RFSA?  (at what frequencies, and with what linewidths)

professor 出的 我认为是拍频,他说不对...求高手解答!!
