Targeted Optical Control of an Active Medium Embedded In Photonic Crystals

Hiroyuki Nihei, Atsushi Okamoto

Abstract

We demonstrate optical control of an active medium, such as a quantum dot or an impurity atom, embedded in three-dimensional photonic crystals. The optical control provides a very high spectral selectivity, which allows us to control confined light near a targeted active medium with a specific resonant frequency. Using such an optical control, even if the other active mediums are embedded nearby, we may selectively control only the targeted active medium, leading to a basic operation of an optical memory on the nanoscale below the light wavelength.

Nanophotonic quantum dot embedded in photonic crystals using a coherent control with a high spectrum resolution

Fumiaki Matsuoka, Hiroyuki Nihei, Atsushi Okamoto

We demonstrate that the emission spectrum from a quantum dot near the edge of a photonic band gap (PBG) can be spectrally resolved on the subwavelength scale using coherent control. In the case of the coherent control, confined light near a quantum dot embedded in photonic crystals can be released by changing the phase of the external laser phase, without closing the PBG. Moreover, in this demonstration, we examine the spectrum resolution of the coherent control, which indicates that the spectrum resolution is the subwavelength scale. Therefore, even if there are many quantum dots are embedded in photonic crystals, we can be operated a quantum dot with a specific resonant frequency. This technique may provide a basis for N-qubit operation for quantum computations and nanophotonic devices.

Manipulating light with strongly modulated photonic crystals

Masaya Notomi

Recently, strongly modulated photonic crystals, fabricated by the state-of-the-art semiconductor nanofabrication process, have realized various novel optical properties.This paper describes the way in which they differ from other optical media, and clarifies what they can do.In particular, three important issues are considered: light confinement, frequency dispersion and spatial dispersion.First, I describe the latest status and impact of ultra-strong light confinement in a wavelength-cubic volume achieved in photonic crystals.Second, the extreme reduction in the speed of light is reported, which was achieved as a result of frequency dispersion management.Third, strange negative refraction in photonic crystals is introduced, which results from their unique spatial dispersion, and it is clarified how this leads to perfect imaging.The last two sections are devoted to applications of these novel properties.First, I report the fact that strong light confinement and huge light-matter interaction enhancement make strongly modulated photonic crystals promising for on-chip all-optical processing, and present several examples including all-optical switches/memories and optical logics.As a second application, it is shown that the strong light confinement and slow light in strongly modulated photonic crystals enable the adiabatic tuning of light, which leads to various novel ways of controlling light, such as adiabatic frequency conversion, efficient optomechanics systems, photon memories and photons pinning.
