We demonstrate a distortion free tunable delays as long as 72 ps with a 10 GHz bandwidth using thermally tuned silicon microring resonators. The device is compact measuring only 30 mum wide by 250 mum long.
We report the fabrication and experimental verification of a multiwavelength high-speed 2 times 2 silicon photonic switch for ultrahigh-bandwidth message routing in optical on-chip networks. The structure employs only two microring resonators in order to implement the bar and cross states of the switch. These states are toggled using an optical pump at 1.5-mum wavelengths inplane with the waveguide...
We demonstrate a wideband invisibility cloak in the optical regime composed of nanometer scale non-resonant dielectric structures. The cloak conceals a deformation on a reflecting surface, under which an object can be hidden.
We demonstrate significant reduction of one of the main nonlinear loss mechanisms in silicon waveguides-free carrier absorption. We show reduction of the free-carrier lifetime from 3 ns down to less than 12.2 ps.
We demonstrate GHz-speed electro-optic modulation using microring resonators in a deposited layer of polycrystalline silicon. Active optical devices in a deposited microelectronic material can enable monolithic large-scale integration of photonic networks on a microelectronic chip.
We demonstrate, for the first time, an electro-optically tunable delay element on a silicon micro-chip. We show tunable delays between 5.51 ps to -28 ps, corresponding to group indices between 37.2 and -190.
We demonstrate low loss silicon waveguides fabricated without silicon etching by selective oxidation. We show propagation losses of 0.3dB/cm (lambda=1.55 mum), roughness of 0.3 nm RMS, and 0.0002 dB loss for a 90deg bend with 20 mum bending radius.
A 2 times 2 multi-wavelength silicon switch, enabling low-power on-chip message routing with ultra-compact footprints, is designed, fabricated, and tested with switching ratios, transition times, and power penalties reported.
