A semiconductor laser amplifier-reflector for the future FTTH applications

Next Generation of Optical Access Network Based on Reflective-SOA

“…The first integrated RSOA for optical communication appeared in 1996 where the device was employed for upstream signal modulation at a bit rate of 100 Mbit/s (Feuer et al, 1996). Then several experiments based on RSOAs for local access network were realized where the bit rate was increased to 155 Mbit/s (Buldawoo et al, 1997). In this chapter, we mainly focus on the wavelength upgrade scenario for WDM-PON systems.…”

Compact Wireless Access Nodes for WDM Bidirectional Radio-over-Fiber System Based on RSOA

“…Recent research has shown that optical envelope detection techniques, without RF oscillator and mixer, satisfactorily perform reception of RoF signals [2,3]. On the other hand, reflective semiconductor optical amplifier (RSOA) operating as a modulator at an optical network unit (ONU) is a promising component to implement a bidirectional system because of its attractive features related to its multi-functionalities of optical amplifier and modulator [4][5][6]. Very recently, we have also proposed a bidirectional RoF system with phase modulation uplink and oscillator-free downlink by employing an RSOA, which acts simultaneously as an intensity modulator and an optical envelope detector [7].…”

1.3 µm vertical-cavity amplifying switch

“…60, 2001. networks with a centralized light source. Several proposed solutions for access and fiber to the home (FTTH) networks take this approach, instead of using conventional transceivers, in order to minimize component cost [7][8][9]. In the configuration in Ref.…”

“…In the configuration in Ref. [8] SOAs are used both to detect the incoming signal at the remote nodes and to modulate a continuous wave (CW) signal for the upstream information. A VCSOA showing amplifier-detector dual functionality has already been demonstrated [10].…”
