⏹Light detectors(光探测器）⏹Light can be detected by the eye. The eye is not suitable for modern fiber眼睛可以探测到光。
但是眼睛不适合用在现在的光线通信上因为它的反应太慢了。
communications because its response is too slow, its sensitivity to low-level signals is它的敏感度对于低频信号来说太不足了，而且对于电子接收器进行调幅解码还有其他信号处理也不是很简单。
inadequate, and it is not easily connected to electronic receivers for amplification,decoding, or other signal processing. Furthermore, the spectral response of the eye is而且眼睛的光谱响应仅限于0.4和0.7UM 之间的波长，而这也正是光损失最多的波长。
limited to wavelengths between 0.4 and 0.7 u m, where fibers have high loss.Nonetheless, the eye is very useful when fibers are tested with visible light. Break and虽然如此，眼睛在用光纤探测可见光时是非常有用的。
终止和打断能够通过观察散射的光观察到discontinuities can be observed by viewing the scattered light.⏹System, such as couplers and connectors, can be visually aligned with the visiblesource before the infrared emitter is attached. The remainder of this chapter is confined to an investigation of devices that directly convert optic radiation to electrical signals (either current or voltage) and that respond quickly to changes in the optic power level.⏹Principles of Photodetection⏹We will look at two distinct photodetection mechanisms. The first is the externalphotoelectric effect, in which electrons are freed from the surface of a metal by the energy absorbed from an incident stream of photons. The vacuum photodiode and the photomultiplier tube are based on this effect. A second group of detectors are semiconductor junction devices in which free charge carriers (electrons and holes) are generated by absorption of incoming photons. This mechanism is sometimes called the internal photoelectric effect.⏹hree common devices using this phenomenon are the pn junction photodiode, the最常用的应用这个现象的手段是pn节光电二极管，pin二极管，还有雪崩二极管PIN photodiode, and the avalanche photodiode.⏹Important detector properties are responsivity, spectral response, and rise time. The重要的探测要素有敏感度，光谱响应，还有回升时间。

光电技术英文讲义pdfPhotonic Technology: Illuminating the FuturePhotonic technology, the science and application of light, has revolutionized countless industries and transformed the way we live, work, and communicate. From the ubiquitous LED bulbs that light our homes to the fiber-optic cables that transmit data at lightning speeds, photonic technology has become an integral part of our daily lives. In this comprehensive essay, we will explore the fascinating world of photonic technology, its diverse applications, and its profound impact on our society.At the heart of photonic technology lies the manipulation and control of light. Photons, the fundamental particles of light, possess unique properties that make them invaluable tools in various fields. The ability to generate, transmit, and detect light with precision has enabled a wide range of technological advancements, from telecommunications to medical diagnostics to energy production.One of the most prominent applications of photonic technology is in the field of telecommunications. The development of fiber-optic communication systems has revolutionized the way we transmit dataover long distances. Fiber-optic cables, which use light to carry digital information, offer several advantages over traditional copper wires, including higher bandwidth, lower signal loss, and greater immunity to electromagnetic interference. This has enabled the rapid growth of high-speed internet, global data networks, and real-time communication services, transforming the way we connect and share information around the world.Beyond telecommunications, photonic technology has also made significant strides in the medical field. Techniques such as laser surgery, optical imaging, and spectroscopic analysis have transformed the way healthcare professionals diagnose and treat various medical conditions. Lasers, for example, have become indispensable tools in ophthalmology, allowing for precise and minimally invasive procedures to correct vision problems. Optical imaging techniques, such as magnetic resonance imaging (MRI) and optical coherence tomography (OCT), provide detailed, non-invasive insights into the human body, enabling earlier detection and more effective treatment of diseases.In the realm of energy production, photonic technology has played a crucial role in the development of renewable energy sources. Photovoltaic cells, the backbone of solar power systems, rely on the photovoltaic effect, where light energy is converted into electrical energy. The ongoing advancements in solar cell efficiency and cost-effectiveness have made solar power an increasingly viable and widespread alternative to traditional fossil fuels, contributing to the global shift towards sustainable energy solutions.The applications of photonic technology extend far beyond these examples. In the field of manufacturing, laser-based tools have revolutionized precision cutting, welding, and material processing, enhancing productivity and quality. In the realm of defense and security, photonic sensors and imaging systems are used for surveillance, target detection, and missile guidance. In the scientific community, advanced photonic instruments, such as telescopes and spectroscopes, have unlocked new frontiers in astronomy and fundamental physics research.As photonic technology continues to evolve, its impact on our daily lives is only expected to grow. Emerging technologies, such as quantum computing, augmented reality, and directed-energy weapons, all rely on the unique properties of light to push the boundaries of what is possible. The continued research and development in photonic technology will undoubtedly lead to further breakthroughs and innovations that will shape the future of our world.In conclusion, photonic technology is a field of immense importance and vast potential. From revolutionizing communication networks toadvancing medical diagnostics and treatment, from powering renewable energy sources to enabling groundbreaking scientific discoveries, the impact of photonic technology is truly profound. As we continue to harness the power of light, we can expect to see even more remarkable advancements that will transform the way we live, work, and interact with the world around us.。

光一般被定义介于红外和紫外之间、可被裸眼看到的电磁波谱的一部分。
Optics plays an influential role in our lives:光学在我们的生活中起着重要作用:When you look into a mirror in the morning to comb your hair, when you see a rainbow after it rains, in medical devices that save lives, as you read this page, as you see, optics is at work.当你在早晨面对一面镜子梳你的头发时，当你在雨后看到彩虹时，在那些挽救生命的医学设备里，当你读这篇文章时，如你所见，是光在工作。

22 The Dual Nature of Light(光的二重性)The nature of light has been a controversy debated throughout the course of history. Two models evolved: the wave model and the particle model. Each model has taken an important dominating place, but neither has been disproved completely. Therefore, the scientific community has combined the two theories to form the wave particle duality, where characteristics from both models are attributed to light (the “wavicle”). These two seemingly contradicting models have been reconciled by a new theory of physics, called quantum electrodynamics, which is a quantum theory of the electromagnetic interactions between photons, electrons and muons (an elementary particle having a mass around 200 times greater than an electron). This model is also known as quantum theory of light., controversy n. , , 争论辩论论战;, debate v. 争论, 辩论, dominating adj. 专横的, 主要的, 独裁的, disprove vt. 反证;反驳;证明…为伪, wavicle [物][量子]波粒二象性, attribute vt.

[核]基本粒子光的本性在其整个历史过程中是一场辩论。
它们发展成两种模式:波动模型和粒子模型。
每一种模型都有其重要的专用位置，但是没有任何一个可以被完全证明为误。
因此，科学界将这两种理论结合而形成波粒二象性，而来自于两种模型的特征可以归因于光(波粒二象性)。
这两种看似矛盾的模型被一种新的物理理论所统一，即量子电动力学，是一种光子，电子和μ介子(某一体积比单个电子大大约200倍的基本粒子)之间的电磁相互作用的量子理论。
这个模型也被称为光的量子理论。
The Wave Theory of Light:光的波动理论The theory that light is transmitted via wave form was proposed by Christian Huygens in 1679. According to his theory:光以波动形式传播的理论是克里斯蒂安?惠更斯在1679年提出的，根据他的理论:(克里斯蒂安?惠更斯:(Christian Huygens 1629-1695)是与牛顿同一时代的科学家，是历史上最著名的物理学家之一，他对力学的发展和光学的研究都有杰出的贡献，在数学和天文学方面也有卓越的成就，是近代自然科学的一位重要开拓者。
