We examine the influence of disorder over millimeter lengthscales, in the transport of photons. Super-collimation is achieved for varying controlled degrees of disorder in large-scale measurements, supported by physical theory and simulations.
We present measurements and modeling of collimating surface states in slow-light photonic crystal superlattices consisting of alternating dispersive and homogeneous media. Superlattice periodicity allows evanescent-wave resonant coupling to surface photon bound states, supporting collimation.
We present experimental observations of self-collimation effect in photonic crystal superlattices consisting of photonics crystal region and homogeneous media. The high-resolution near-field scanning optical microscopy is supported by precise nanofabrication, and rigorous 3D-FDTD simulations.
We present the integrated chip-scale tuning of multiple photonic crystal cavities. The optimized implementation allows for large tuning (20K/mW), with deterministic resonance control towards all-optical analogue to electromagnetically-induced-transparency on-chip.
