Fully-automated optimization of grating couplers
Logan Su, Rahul Trivedi, Neil V. Sapra +3
We present a gradient-based algorithm to design general 1D grating couplers without any human input from start to finish, including a choice of initial condition. We show that we c…

Inverse design and demonstration of a compact on-chip narrowband three-channel wavelength demultiplexer
Logan Su, Alexander Y. Piggott, Neil V. Sapra +2
In wavelength division multiplexing (WDM) schemes, splitters must be used to combine and separate different wavelengths. Conventional splitters are fairly large with footprints in…
