Photonic crystals: controlling spectral, spatial and reciprocal properties of light

Shanhui Fan, Mehmet Fatih Yanik, Xiaojun Yu, Jonghwa Shin, Z. Wang

Abstract

We show that photonic crystals can be used to stop, store, and time-reverse light pulses; to suppress diffraction and enable remarkable reflection properties at interfaces; and to create non - reciprocal devices that are extremely compact.

Nanophotonics: Stopping Light, Nonreciprocity, and Metamaterials

Shanhui Fan, Mehmet Fatih Yanik, Z. Wang +3 more

In this paper we review our recent works in developing photonic crystals and nanophotonic structures for the control of light. We show that dynamic crystal structures, in which the refractive index of the material is modulated by a small extent while a photon pulse is in the crystal, can be used to stop, store and even time-reverse light pulses [ 1][ 2][ 3]. We also show that by incorporating magneto-optical effects into the crystal structures, the reciprocity of light can be broken, resulting in uni-directional devices that are extremely compact [ 4]. And finally, by exploiting sub-wavelength electromagnetic resonances in meta structures, new meta-materials can be created. These materials feature frequency-independent refractive index that is controlled by geometry and can be arbitrarily large [ 5]. Such materials can be of importance for integrated optics and image sensing applications.

Dynamic Photonic Crystals

Shanhui Fan, Mehmet Fatih Yanik, Michelle L. Povinelli +1 more

When dynamic behaviors are introduced into photonic crystal systems, fascinating new possibilities emerge. For example, the bandwidth of a pulse can be completely compressed to zero, resulting in on-chip all-optical stopping and storage of light pulses. The pulse spectrum can also be inverted around a center frequency to time-reverse an optical pulse.

Strong fluorescence suppression in polymer inverse opals

Pieter-Jan Demeyer, Thierry Verbiest, Koen Clays

Modern demands for high speed telecommunication and data processing have created the need for advanced materials that allow active manipulation of light waves. Subsequent research has shown that photonic crystals provide excellent candidates to accommodate these needs. Photonic crystals are a relatively new class of materials in which the refractive index is periodic in 1, 2 or 3 dimensions. This periodicity gives rise to a photonic band gap which in turn provides selective reflection of certain wavelengths of light. Another interesting property of photonic crystals is the anomalous dispersion that occurs close to the photonic band gap (i.e. at the band edge). The anomalous dispersion causes the group velocity of light to decrease considerably, allowing stronger interactions between the travelling light and the material of which the photonic crystal consists

Tunable photonic crystals enable new optical physics and devices

Shanhui Fan, Mehmet Fatih Yanik, Won Joo Suh

We show that tunable photonic band gap materials offer new opportunities for device applications. Optical switches or sensors that are far more compact and sensitive, for instance, can be constructed when we introduce either optical or mechanical tunability into photonic crystal structures. Furthermore, when we tune the photonic crystal while a photon is inside the crystal, the crystal can exhibit qualitatively different optical physics effects. As a particularly exciting example, we show that light can in fact be completely stopped in a tunable photonic crystal, and the conventional delay bandwidth product limit in resonator optics can be completely overcome.
