Summary of the technology
A new method for increasing the bandwidth in bidirectional optical links and passive optical networks has been developed and patented. This method uses a flexible simple, integrated and wavelength-agnostic semiconductor device to achieve re-modulation of the incident seed light with simultaneous phase and intensity modulation. Partners to further develop the system and/or to establish commercial agreements along with technical cooperation are sought.
is to provide a higher transmission bandwidth at the same clock rate, for avoiding extra heating and power consumption. In the same way as new computers are nowadays challenged to provide higher computation capacity at the same clock rate also for avoiding excessive CPU heating.
The new developed technology takes advance of commercial devices and provides a new method for multiplying the bandwidth provided to the home-user by simultaneous modulation of the phase and intensity of the transmitted light.
Moreover, as the commercial device is wavelength-agnostic, this enhance of the optical bandwidth can be provided at any channel of the WDM-PON to be decided by the operator of the network, providing an important flexibility.
