In this study, we aim to fabricate the structure that has multi-frequency resonances with the artificial materials called metamaterials. We designed and fabricated the coupled resonator structures where some resonators had interactions with each other through electromagnetic coupling. In these structures, the multi frequency resonant behavior was observed both in simulation and experiment. In addition, we fabricated metamaterial absorbers operated in terahertz region by utilizing those coupled resonator structures.

This research develops thermal imaging which visualizes the distribution of electromagnetic waves by observing temperature rise induced by absorption on a two-dimentional artificial structure, called metasurface. By imposing symmetry condition called self-complementarity on a checkerboard-like metasurface, efficient thermal imaging can be expected in broad spectral regions. The simulations, which compute heat induced by electromagnetic waves and its thermal diffusion, showed higher temperature rise in resistive sheets at the corners of the checkerboard structure compared with an uniform resistive sheet. In our experiment, which observed fabricated metasurfaces illuminated by microwave using a thermography, we observed significant temperature rise localized at the resistive sheets, and shown that the devise can be employed for effective and broadband thermal imaging.

It is possible to control the velocity of surface plasmon propagating on a structured metallic surface by designing the two-dimensional structure. In this project, we focused on a flat band, where the surface plasmon is completely localized. We proposed a metallic structure to realize the flat band for all wavevectors, and performed experimental demonstration in terahertz regions. The formation of the flat band was verified by the transmission measurement of the plane wave and an attenuated total reflection method. In addition, the extremely slow propagation of the surface plasmon unique to the flat band was demonstrated through electromagnetic simulation by computing the time evolution of the surface plasmon on the structured metallic surface.

The purpose of the project is to propose novel methods for optical measurements using optical systems designed on the basis of the time-reversal symmetry, and to experimentally demonstrate the proposed optical measurements for the applications of various ultra-sensitive measurements beyond conventional methods. In particular, we focus on time-reversal optical systems inspired by two-photon interference using time-correlated photon pairs, and demonstrated phase superresolution in two-photon interference and dispersion cancellation in optical coherence tomography with classical light. These applications have been demonstrated using purely quantum light with extremely low intensity. On the other hand, the proposed methods enable us to obtain intense signals from strong classical light with high efficiency, and they are expected to lead to the development of more practical sensitive measurements.

We have proposed new concepts such as no-reflection condition for chiral medium and frequency-independent response of self-complementary meta-surface. We have demonstrated storage of electromagnetic waves and enhancement of second harmonic generation with coupled-resonator-based metamaterials. In the analysis of plasma metamaterials, we have comfirmed dynamic negative-refractive-index and nonlinearity enhancement (bifurcation and harmonic generation). Metamaterials with arbitrarily shaped elements have been proposed and developed by using the genetic algorithm based on the electromagnetic field analysis. The proposed methods have been verified numerically and experimentally. We theoretically derived circuit models for metallic structures from Maxwell equation. They give us physical insights of electromagnetic phenomena in metamaterials.

We realized electromagnetically induced transparency (EIT) using metamaterial, which is an assembly of subwavelength artificial atoms, and investigated methods to control EIT properties. In microwave regions, we realized a method to control the propagation delay by the incident angle and a method to control the EIT properties by applied voltages. As an application of the latter method, we demonstrated storage and retrieval of a pulse in the metamaterial. We also achieved efficient frequency mixing using EIT metamaterial with nonlinear elements.

今年度は、昨年より行っていた、光電子増倍管の光電面での2光子吸収を利用した光子対の検出の研究以外に、新たな光子対生成法である、4光波混合を用いた光子対生成について研究を行った。4光波混合を起こす媒質は数多くあり、通常の光ファイバを用いた研究が最近になり盛んになってきたが、本研究では、フォトニック結晶ファイバを用いた光子対の生成に取り組んだ。非線形性の高いフォトニック結晶ファイバを利用することにより、高い変換効率が期待できる上に、ゼロ分散波長も自在に設計できるので、生成可能な光子対の波長の自由度が高まる。研究の結果、ポンプ光波長を調整することで、非常に広いスペクトルの光子対を得ることに成功した。実験では、760.4nmの波長のポンプ光を入射して生成された光子対のうち、660nmの光子をシグナル光子、900nmの光子をアイドラ光子として同時計数を行い、光子対の生成の確認した。さらに、生成された光子対を非対称マッハツェンダー干渉計に導入し2光子干渉実験を行った結果、83%の明瞭度の2光子干渉縞を観測することができた。これは、古典的電磁気学で説明がつく限界の明瞭度(50%)を越えており、光子対間に量子的な時間相関が存在することを意味する。光子対の生成に4光波混合を利用することで、ポンプ光と同程度の波長の光子対を生成することができる。これにより、短波長の光子対を生成することが容易になると考えられ、回折限界を超える高分解干渉法に有用な方法であると考えている。

本年度(平成17年度)は、まず、前年に行ったコヒーレント光を用いた実験を進め、後の光子対の実験で必要となるパラメータを導き出すことにした。光電子増倍管の光電面(バイアルカリ金属)におけるカスケード2光子遷移を対象とし、この光電面に1064nmの波長のレーザ光を入射することで誘起される2光子電流を測定することを試みた。そして、入射光強度に対する光電流が2乗に比例することや、ビーム断面積に対して光電流が反比例するという理論通りの結果が得られた。実験の結果、測定可能な光子対の出力は100nW以上はいることが分かった。
これを元に、本来の目的である自発パラメトリック下方変換過程によつて発生した時間相関のある光子対を用いた2光子遷移の実験を行った。高出力の光子対がいることから、疑似位相整合導波路型PPLN素子を利用することにした。ポンプには532nmの波長で200mW出力の固体レーザを利用した。素子の温度を制御することで、最大200nW程度の光子対ビームが得られた。コヒーレント光を用いた実験より光強度はこれで十分だと思われたが、実験では光電流は検出されなかった。これは、プリズム1つを用いて、ポンプ光(532nm)と光子対(1064nm)の分離を行った際に、広いスペクトル帯域をもつ光子対の波長分解が起こってしまったからと考えられる。これに対しては、プリズムの代わりにフィルターを用いてこの問題は克服できると考え実験を行っている。
実験と並行して光子対による2光子吸収の理論的考察も行った。2光子吸収と相互作用する光の場を2光子波動関数を用いて表現することで、任意の2光子状態に対する2光子遷移を定式化することができた。そして、2光子吸収の大きさは二光子波動関数の形に敏感に影響されることが分かった。今後は、このことを実験的に確かめることも予定している。 -
