Innovative reflective semiconductor optical amplifier optimised for next-generation passive optical networks

2 May 2007 Opto-Electronics

At OFC 2007, photonics supplier CIP launched an innovative reflective semiconductor optical amplifier (RSOA) family which offers both the performance and economy needed to implement advanced PONs (passive optical networks) based on wavelength division multiplexing (WDM).

Capable of delivering more than 20 dB of optical gain, CIP claims the new component provides optical data transmission at rates up to 1,25 Gbps - without need for either a local wavelength stabilised source or temperature control. This combination of performance and economy for consumer optical network unit (ONU) applications, provides a platform for access network providers to boost performance radically compared with today's EPON/GPON (Ethernet/Gigabit-capable) PON technologies.

To support the cost and manufacturing demands of access network companies, the RSOA component is being made available in a low-cost TO-56 can package, for easy integration into micro-optic assemblies for consumers. The RSOA device itself is monolithic, and fabricated using a proven InP (indium phosphide) process that is well suited to high-yield volume manufacture.

CIP's RSOA component provides high-speed transmission capability for clients in WDM-PON networks by reflecting and modulating a 'seed' light that is transmitted throughout the network. Light from a broadband source can be split into different wavelengths easily for use in different segments of the network by means of an arrayed waveguide grating (AWG) - a readily available component. This architecture allows the RSOA to deliver dedicated gigabit optical data transmission facility to clients in fibre-to-the-home/premises (FTTH/FTTP) access network architectures - without the expense of a tuneable wavelength source at the ONU.
