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 19):
The method of  claim 17 , wherein forming the first waveguide and the second waveguide further comprises selecting proper core materials and lengths respectively for the first waveguide and the second waveguide and cladding material for the first cladding material such that a combination of the first waveguide and the second waveguide is constrained to an athermal condition that a temperature variation of a first effective index of refraction multiplied by a first length of the first waveguide cancels a temperature variation of a second effective index of refraction multiplied by a second length of the waveguide.
