Abstract :
We demonstrate subwavelength grating devices in silicon-on-insulator including Bragg gratings, racetrack resonators, and optical delay lines. The Bragg grating filter has a 3 dB bandwidth of 0.5 nm and a reflectivity of 90%; the racetrack resonator has a 3 dB bandwidth of 1 nm, a free spectral range of 4.6 nm, and an extinction ratio as high as 33 dB; the optical delay lines achieve ~30ps time-delay with 30% change in duty-cycle.
