Abstract:
A silicon photonics based temperature-insensitive delay line interferometer (DLI). The DLI includes a first arm comprising a first length of a first material characterized by a first group index corresponding to a first phase delay to transfer a first light wave with a first peak frequency and a second arm comprising a second length of a second material characterized by a second group index corresponding to a second phase to transfer a second light wave with a second peak frequency with a time-delay difference relative to the first light wave. The first phase delay and the second phase delay are configured to change equally upon a change of temperature. The time-delay difference between the first light wave and the second light wave is set to be inversed value of a free spectral range (FSR) to align at least the first peak frequency to a channel of a designated frequency grid.

Claim (Index 10):
The photonics device of  claim 9  further comprising a heater disposed over the third length of the first extra section that is thermally isolated from the first length of the first material and the second length of the second material for generating a local-temperature-induced frequency shift to compensate any offset of the first peak frequency away from a standard channel frequency of the designated frequency gird caused by the change of the ambient temperature.
