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 11):
A system comprising:\n a delay line interferometer with temperature insensitive characteristics comprising: a first waveguide arm comprising a first plurality of segments connected in series to transfer a first light wave of a first peak frequency at an ambient temperature, each of the first plurality of segments being characterized by one of the first plurality of lengths and a material-specific group index; a heater disposed near at least one of the first plurality of segments to set a second temperature locally; a second waveguide arm comprising a second plurality of segments connected in series to transfer a second light wave of a second channel frequency with a time-delay difference relative to the first light wave at the same ambient temperature, each of the second plurality of segments being characterized by one of the second plurality of lengths and a material-specific group index; wherein a first change of phase-delay of the first waveguide arm for transferring the first light wave is configured to be equal to a second change of phase-delay of the second waveguide arm for transferring the second light wave upon any change of the ambient temperature, and the time-delay difference between the first light wave and the second light wave is equal to an inversed value of a free spectral range (FSR) associated with a designated frequency grid, and the second temperature is set above the ambient temperature to induce a frequency shift to align at least the first peak frequency to a channel frequency of the designated frequency grid; and a network.
