Abstract:
An optical dispersion compensator integrated with a silicon photonics system including a first phase-shifter coupled to a second phase-shifter in parallel on the silicon substrate characterized in an athermal condition. The dispersion compensator further includes a third phase-shifter on the silicon substrate to the first phase-shifter and the second phase-shifter through two 2×2 splitters to form an optical loop. A second entry port of a first 2×2 splitter is for coupling with an input fiber and a second exit port of a second 2×2 splitter is for coupling with an output fiber. The optical loop is characterized by a total phase delay tunable via each of the first phase-shifter, the second phase-shifter, and the third phase-shifter such that a normal dispersion (>0) at a certain wavelength in the input fiber is substantially compensated and independent of temperature.

Claim (Index 1):
An optical dispersion compensator integrated with a silicon photonics system comprising:\n a first phase-shifter on a silicon substrate; a second phase-shifter on the silicon substrate; a first 2\u00d72 splitter having a first exit port coupled to an input port of the first phase-shifter and a second exit port coupled to an input port of the second phase-shifter; a second 2\u00d72 splitter having a first entry port coupled to an output port of the first phase-shifter and a second entry port coupled to an output port of the second phase-shifter; a third phase-shifter on the silicon substrate having an input port coupled to a first exit port of the second 2\u00d72 splitter and an output port coupled to a first entry port of the first 2\u00d72 splitter to form an optical loop with the first phase-shifter and the second phase-shifter; wherein the second entry port of the first 2\u00d72 splitter is for coupling with an input fiber and the second exit port of the second 2\u00d72 splitter is for coupling with an output fiber, wherein the optical loop is characterized by a total phase delay tunable via each of the first phase-shifter, the second phase-shifter, and the third phase-shifter such that a normal dispersion (>0) at a certain wavelength in the input fiber is substantially compensated and independent of temperature.
