In this paper, we propose a dynamic reconfigurable wavelength division multiplexed (WDM) millimeter-waveband radio-over-fiber (RoF) and baseband access network. We also demonstrate dynamic channel allocation capability of millimeter-waveband optical RoF and baseband signals in WDM access network using a supercontinuum (SC) light source, arrayed-waveguide gratings, and a reconfigurable optical crossconnect switch. The dynamic reconfigurable RoF and baseband network architecture is presented and its features are described. Two 155-Mb/s RoF channels and two 2.5-Gb/s baseband channels are effectively generated, transmitted through 25 km of fiber, switched, and then transmitted again through 2 km of fiber and detected with error-free operation (bit error rate< 10-9). The proposed architecture allows the RoF and baseband to coexist and is highly scalable, both in terms of channel counts and access point (AP) counts. [ABSTRACT FROM PUBLISHER]

We will propose a dynamic reconfigurable wavelength-division-multiplexed (WDM) millimeter-waveband (mm-waveband) radio-over-fiber (RoF) access network and demonstrate, for the first time, a dynamic-channel-allocation capability of millimeter-waveband optical RoF signals in WDM access network using a supercontinuum light source, arrayed-waveguide gratings, and a reconfigurable optical-crossconnect switch. The dynamic reconfigurable RoF network architecture is presented, and its features are described. Then, four 155-Mb/s RoF channels are effectively generated, transmitted through 25 km of fiber, switched, transmitted again through 2 km of fiber, and detected with an error-free operation (bit error rate < 10-10). The proposed RoF architecture is highly scalable, both in terms of channel and access-point counts. [ABSTRACT FROM PUBLISHER]

We show a bidirectional optical access network with dynamic channel allocation capability of decimeter-wave band optical radio-over-fiber (RoF) and baseband signals. The network can be configured enabling peer-to-peer connectivity, and is based on a simple access point (AP) unit. The proposed RoF architecture is highly scalable, both in terms of channels and APs.

We demonstrate a time-slotted full-duplex analog/digital hybrid radio-over-fiber access network unit. A reflective semiconductor optical amplifier at the access point is used to erase the downlink 1.5-Gb/s baseband signal for 60-GHz-band 155-Mb/s uplink signal on the reused optical carrier.

We propose a simple demultiplexer for dense wavelength-division-multiplexed (DWDM) milllimeter-wave-band radio-over-fiber (RoF) systems that uses an optical-frequency-interleaving technique, which consists of only a 2 x N arrayed waveguide grating with an optical coupler. In the proposed demultiplexer, a suppression ratio of more than 25 dB against adjacent channels is experimentally obtained. The transmission performance of 12-channel DWDM 60-GHz-band RoF signals with 25-GHz channel spacing over 25-and 2-km standard single-mode fibers via the proposed demultiplexer achieves a bit-error rate of less than 10-9.

The differential-phase-to-intensity conversion (DPIC) can be used to detect an optical phase-shift of laser light. The system is based on injection locking of a semiconductor laser. We have now found the waveform of a DPIC signal can be adjusted by controlling and selecting the polarization of the lightwaves before and after the slave laser. We experimentally investigated the phenomenon, and concluded that it originated in TM-mode excitation and interference between the TE and TM modes within and after the slave laser. Such adjustment of the waveform according to the condition of polarization is useful because it can achieve direct demodulation of an optical DPSK signal without using an electrical circuit. The adoption of the DPSK signal format enables a higher bit rate than the original DPIC scheme. We demonstrated direct detection of an OC-192 (9.95328 Gb/s) DPSK signal by using polarization-controlled DPIC. [ABSTRACT FROM PUBLISHER]
