Bidirectional Radio-Over-DWDM Transport Systems Based on Injection-Locked VCSELs and Optoelectronic Feedback Techniques

A bidirectional radio-over-dense-wavelength-division-multiplexing transport system using injection-locked and optoelectronic feedback controlled vertical-cavity surface-emitting lasers (VCSELs) is proposed and demonstrated. It is shown that the system performance, which is evaluated by using bit-error rate, error vector magnitude, and intermodulation distortion-to-carrier ratio, is improved due to using injection-locked and feedback controlled VCSELs

A Full-Duplex Radio-on-Photonic Crystal Fiber Transport System

A full-duplex radio-on-fiber transport system based on wavelength-division-multiplexing and optical add-drop multiplexing techniques, as well as proper length of photonic crystal fiber (PCF) is proposed and demonstrated. Over a combination of single-mode fiber and PCF transmission, low third-order intermodulation-distortion-to-carrier ratio (IMD3/C) and bit-error-rate values were obtained in our proposed systems. Such a proposed full-duplex radio-on-PCF system is suitable for the long-haul microwave optical links

Employing Mutually Injection-Locked Fabry-Perot Laser Diodes to Setup a Hybrid WDM Transport System

A hybrid WDM transport system based on mutually injection-locked Fabry-Perot laser diodes (FP LDs) for CATV, 256-QAM and OC-48 transmission is proposed and demonstrated. Mutually injection-locked FP LDs as broadband light source could be relatively simple and cost-effective compared with other demonstrated light source schemes.

Employing VCSELs Injection-Locked and Optoelectronic Feedback Techniques to Setup a Bidirectional Radio-on-DWDM Transport System

A bidirectional radio-on-DWDM transport system based on VCSELs injection-locked and optoelectronic feedback techniques is proposed and demonstrated. Good performances of BER, EVM, and intermodulation distortion to carrier ratio (IMD/C) were obtained in our proposed bidirectional radio-on-DWDM transport systems.

Employing photonic crystal fiber to improve composite second-order and composite triple-beat performances in a two-wavelength wavelength-division-multiplexing transport system

A two-wavelength wavelength-division-multiplexing (WDM) externally modulated transport system employing photonic crystal fiber (PCF) as a dispersion compensation device to compensate the fiber dispersion and to reduce the cross-phase modulation (XPM)–induced cross talk is proposed and demonstrated. In comparison with a two-wavelength WDM externally modulated transport system without a dispersion compensation device or with a conventional dispersion compensating fiber (DCF) as a dispersion compensation device, good performances of composite second-order (CSO) and composite triple beat (CTB) were obtained accompanied by acceptable carrier-to-noise ratio (CNR) in our proposed system.

Radio-on-PHS/VICS/ETC/SB DWDM transport systems

A radio-on-dense-wavelength-division-multiplexing (DWDM) transport system for personal handy system (PHS)/vehicle information and communication system (VICS)/electronic toll collection (ETC)/satellite broadcasting (SB) applications was proposed and demonstrated. Improved performance of bit error rate (BER) over a-100 km of large effective area fiber (LEAF) was obtained. Signal qualities meet the PHS demand with a data signal of 1.9GHz/10Mbps, VICS demand with a data signal of 2.5GHz/12Mbps, ETC demand with a data signal of 5.8GHz/20Mbps, and SB demand with a data signal of 12GHz/25Mbps.
