<P>PROBLEM TO BE SOLVED: To provide a single photon generator that can surely generate a single photon. <P>SOLUTION: Composition gradient is formed in a quantum dot, and a photoexcited electron and a hole are respectively held in a spatially isolated position. When a single photon is generated, an electric field is applied to the quantum dot to recombine the held electron and hole. In this case, the recombination is set in such a timing that a time equivalent to the reuniting life of an exciton molecule formed in the quantum dot is lapsed after photoexcitation. <P>COPYRIGHT: (C)2004,JPO&NCIPI |

フラットパネルディスプレイは、赤外レーザのようなコリメート光源により照射されるプロジェクタ(21−23)と、光線の伝播軸に沿ってある距離に該光線を放つ導波路(1)と、該距離はパネルの縁部への入射角に関係付けられることと、投影された画像を伝播軸と垂直なパネルの面における幅の大きさに拡大するための入力厚板(3)と、赤外光を可視光に変換する蛍光体出力スクリーンとからなる。 導波路内において単色光を使用することにより散乱の問題を低減し、各々が異なる角度で進入する三つ組からなるプロジェクタを使用することによりレジストレーションが比較的簡単にできる。 |

PURPOSE: To obtain an optical communication system by depending upon a phenomenon of mixed phase modulation which varies and controls one or both at the same time of temporal, spatial or both characteristics of spectra of ultra- short light pulses for processing information at a fast repetition rate.
CONSTITUTION: A 1st beam 15 includes a group of pulses of a 1st frequency, a 2nd beam 17 includes a group of pulses of a 2nd frequency and a beam having higher luminance than pulses of the 2nd beam 17 is generated with the pulses of the 1st beam 15. With specific information the pulses of the 1st beam 15 are modulated 18, the 2nd beam is combined to form 25 a 3rd beam 27, a 4th beam 31 is made from a nonlinear material 29 and includes pulses of 1st to 3rd frequencies and pulses of the 3rd frequency are generated from a special effect of mixed phase modulation. The pulses of the 1st frequency are removed through a filter 33, the 4th beam 31 is separated 35 into a 5th beam 37 and a 6th beam 39 and pulses existing in those beams are detected 45 and 47. Consequently, an optical communication system is obtained by using a principle of mixed phase modulation.

PURPOSE:To enable to efficiently convert wavelengths between two difference wavelengths by a bidirectional wavelength conversion element by composing of p-n-p (or n-p-n) type transistor structure of direct transient semiconductor material. CONSTITUTION:A bidirectional wavelength conversion element is composed in a p-n-p type transistor of a p type Ga1-xAlxAs layer 1, an n type Ga1-yAlyAs layer 2 and a p type Ga1-zAlzAs layer 3. An external bias voltage V is applied between the electrodes 4 and 5 so that a reverse bias is applied between the layers 1 and 2 and a forward bias is applied between the layers 2 and 3. The incident light of wavelength lambda1 is introduced to the layer 1 of a band gap Eg1, thereby generating photons. The generated photons are flowed to the layer 2 by a reverse bias electric field applied between the layes 1 and 2. The flowed electrons are injected to the layer 3, and light is emitted to be recombined in this region. |

PURPOSE:To obtain an optical wavelength converter which converts an input light signal directly to an output light signal differing in wavelength by providing a semiconductor P-N junction element having a special function and an optical filter. CONSTITUTION:A source voltage VB is applied to a semiconductor P-N junction element 4 such as semiconductor laser and the element is grounded through a load resistor RL, whereby the implantation current I0 larger than an oscillation threshold is supplied to the element 4. An input light signal of a wavelength lambdai is implanted into the active layer of the element 4 from one terminal thereof and an output light signal is drawn out from the other terminal. The output light signal is passed through an optical filter 5 using, for example, an optical demultiplexer, so that only the light signal of the oscillation wavelength lambdam of the element 4 among the output signals is passed therethrough, whereby the conversion of the optical wavelength is accomplished. Here the phases of the input light signal lambdai and the output light signal are inverted, but the output signal of the same phase is obtainable by performing the similar conversion of the optical wavelength again. |
