Abstract:
A wavelength locker integrated with a silicon photonics transmission system comprising a silicon-on-insulator (SOI) substrate and an input via a power tap coupler to receive a fraction of a transmission signal with one or more frequencies from a primary output path of the silicon photonics transmission system. The wavelength locker further includes a splitter configured to split the input to a first signal in a first path and a second signal in a second path and a first delay-line-interferometer (DLI) coupled to the second path to receive the second signal and configured to generate an interference spectrum and output at least two sub-spectrums tunable to keep quadrature points of the sub-spectrums at respective one or more target frequencies. The wavelength locker is configured to generate an error signal fed back to the silicon photonics transmission system for locking the one or more frequencies at the one or more target frequencies.

Claim (Index 7):
The wavelength locker of  claim 3 , wherein the first DLI further comprises a 2\u00d72 MMI coupler to output the first sub-spectrum and the second sub-spectrum respectively to two signal paths substantially in same power with a relative phase shift equal to half of the free-spectral range, and a resistive heater disposed around the first arm for tuning the interference spectrum in frequency domain to keep the quadrature points of the first sub-spectrum crossing the second sub-spectrum respectively at the one or more target frequencies.
