Abstract
An optical circuit (220) for distributing a plurality of clock signals is presented. The optical circuit includes an optical arrangement (224) and a plurality of transducers (226). The optical arrangement (224) is adapted to receive a primary modulated optical signal and to split the primary modulated optical signal into a plurality of secondary modulated optical signals. The transducers (226) are adapted to convert each secondary modulated optical signal into a corresponding secondary clock signal.
Claims20
An optical circuit for distributing one or more clock signals, the optical circuit comprising
- an optical arrangement adapted to receive a primary modulated optical signal and split the primary modulated optical signal into a plurality of secondary modulated optical signals;
- a plurality of transducers adapted to convert each secondary modulated optical signal into a corresponding secondary clock signal;
- a first input port for receiving a first drive signal derived from a primary clock signal;
- and
- a modulator adapted to receive a first optical signal from a first light source, wherein the modulator is adapted to modulate the first optical signal using the first drive signal to obtain the primary modulated optical signal.
A method of distributing one or more clock signals, the method comprising
- receiving a first drive signal at a first input port, wherein the first drive signal is derived from a primary clock signal;
- receiving by a modulator a first optical signal from a first light source;
- modulating, with the modulator, the first optical signal using the first drive signal to obtain a primary modulated optical signal;
- splitting the primary modulated optical signal into a plurality of secondary modulated optical signals;
- and
- converting, with a plurality of transducers, each secondary modulated optical signal into a corresponding secondary clock signal.
