Applications of optoelectronic devices

This device is made from solid crystalline materials which are lighter than metals and heavier than insulators. Optoelectronics device is basically an electronic device involving light. This device can be found in many optoelectronics applications like military services, telecommunications, automatic access control systems . They utilise energy in the visible and infrared regions of the electromag- netic spectrum.


Solidstate devices like sensors, IR emit- ters, and laser emitters are used for opto- electronic applications.

Using optical and electronic means, it generates, manipulates and converts light.

Photonic devices process, store, transmit and display information for applications such as communications, displays, imaging, memory, biophotonics, energy generation and lighting .

In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrare in addition to visible light. In this chapter we will describe some of the current applications of optoelectronics. In fact lasers, optical fibres and other optoelectronic devices are present in many aspects of our everyday lives. Their use has opened new perspectives in many fields such as medicine, material science, communications, etc.


All the optoelectronic devices are explained in detail. The concept of threshold frequency is also explained. The detection of terahertz and millimeter waves has many applications , but there are still limitations in their technical performance. This chapter discusses in detail the fundamentals and application circuits of different types of optoelectronic devices. Next, the chapter provides definitions of various radiometric and photometric terms commonly used in the field of optoelectronics.


P-n junctions are an integral part of several optoelectronic devices. These include photodiodes, solar cells light emitting diodes (LEDs) and semiconductor lasers. In this section, we discuss the principle of operation of these devices and derive equations for key parameters. Recent progress of research for graphene applications in electronic and optoelectronic devices is reviewe and recent developments in circuits based on graphene devices are summarized.


The bandgap–mobility tradeoff inevitably constrains the application of graphene for the conventional field-effect transistor ( FET) . Nanostructured optoelectronic components have many potential uses in space applications. Outline What is optoelectronics? What Did the Word “Opto-Electronics” Mean? A review is given of recent progress in tetrahedrally bonded amorphous semiconductors and their technological applications to optoelectronic devices. First, some significant advantages of these materials are pointed out, and concrete examples are demonstrated from current technologi- cal topics.


These films with anchored complexes are finding increasing use in energy conversion devices such as dye-sensitized photoelectrochemical solar cells, intercalation batteries, optical display and optical sensors. Principles of operation of these optoelectronic devices are reviewed here. Various approaches to anchoring . Their physical properties are exploited for various potential applications in high- speed digital circuits, microwave and optoelectronic devices. Zhu, Senior Member, IEEE, Felix E. Ejeckam, Student Member, IEEE, Y. Abstract—Direct wafer bonding process has .
