Broadcasting in colorless WDM-PON using spectrum-sliced wavelength conversion

We propose and experimentally demonstrate a novel wavelength-division-multiplexed passive optical network (WDM-PON) scheme for providing broadcasting service by using an inverted amplified spontaneous emission (ASE) from a semiconductor optical amplifier (SOA). In this scheme, single pump signal is converted into multiple wavelengths signal by spectrum sliced wavelength conversion. We expect it could be very practical and cost-effective solution for broadcasting in WDM-PON due to its simplicity.

► Broadcasting over colorless WDM-PON.
► Spectrum sliced method to obtain the wavelength converted signal induced by cross gain modulation in a SOA.
► Single pump signal is converted into multiple wavelength signals for broadcasting.
► Error free transmission of bidirectional 1.25 Gb/s data transmission and 155 Mb/s broadcasting with 100 GHz channel spacing.
