Abstract:
The wavelength response of an arrayed waveguide grating can be tuned, in accordance with various embodiments, using a beam sweeper including one or more heaters to shift a lateral position of light focused by the beam sweeper at an interface of the beam sweeper with an input free propagation region of the arrayed waveguide grating.

Claim (Index 20):
A method comprising:\n in a photonic integrated circuit (PIC) comprising a silicon-on-insulator (SOI) substrate, an array of waveguides formed at least partially within a silicon device layer of the SOI substrate, and a pair of forward and backward heaters disposed at least partially within at least one of a cladding layer or the silicon device layer and laterally overlapping with the array of waveguides, using one of the forward or backward heaters to impart incremental heat-induced phase shifts between adjacent waveguides of the array, the phase shifts imparted by the forward heater being of an opposite sign than the phase shifts imparted by the backward heater.
