We have investigated optical filtering-effects when a spectrally-sliced ASE light is injected to a gain-saturated R-SOA. The resulting distortion in the output optical spectrum from an optical pass-band shape of AWG could significantly affect the transmission quality of the WDM-PON.
Reflection tolerance was improved for long-reach WDM-PON by operating DFB seed-light near its threshold region. With such a spectrally broadened seed light, error-free transmission over 80 km fiber reach was demonstrated under -32dB reflection.
We used wavelength-locked outputs from ASE-injected F-P LDs having narrow mode spacing and asymmetric facet reflectivity as transmitters in a WDM-PON. Trial transmission of HDTV and Ethernet data over the WDM-PON is demonstrated.
We propose and demonstrate a simple passive optical NRZ-to-RZ converter based on an optical filter. This filter could be made of a birefringent device and a polarizer. The measured results show that converted RZ signal is chirp-free and its duty ratio can be adjusted by varying the birefringence of optical filter.
Micron-scale features in holey fibres lead to novel properties including endlessly single-mode guidance, high optical nonlinearity, and anomalous dispersion below 1.3 mum. we review progress in developing high nonlinearity holey fibres for device applications
