| Abstract: | A radio-on-multimode fiber (MMF) system based on vertical-cavity surface-emitting lasers (VCSELs) injection-locked and optoelectronic feedback techniques is proposed and demonstrated. Injection locking and optoelectronic feedback achieves large frequency response of the VCSEL, resulting in good performances of intermodulation distortion to carrier ratio (IMD/C), error vector magnitude (EVM), and bit error rate (BER). Using VCSELs as optical sources in radio-on-MMF systems are very attractive, as they are relatively simple to fabricate and potentially low-cost. Such a proposed radio-on-MMF system is suitable for the short-haul microwave optical links. |
