Thermally controlled Si photonic crystal slow light waveguide beam steering device Open
The doubly periodic Si photonic crystal waveguide radiates the guided slow light into free space as an optical beam. The waveguide also functions as a beam steering device, in which the steering angle is changed substantially by a slight v…

Two-dimensional beam-steering device using a doubly periodic Si photonic-crystal waveguide Open
We demonstrate a nonmechanical, on-chip optical beam-steering device using a photonic-crystal waveguide with a doubly periodic structure that repeats the increase and decrease of the hole diameter. We fabricated the device using a compleme…
