摘要: Optoelectronics (OE) is the technology which employs semiconductor electronic and optical devices to achieve component circuit functionality, can't be achieved alone by electronics. This chapter examines OE important many areas such as signal processing. It also discusses how these work, advantages of approach, future prospects. The begins with solid state laser, one optoelectronic device that outpaces all others, both in total market share R&D investment. followed a discussion status for modifying an beam namely switches modulators. Furthermore, applications technological issues confronting integration components, integrated circuits (OEICs). In implementing pixel arrays, it possible take advantage activity III–V materials their use modulators, lasers non-linear switching elements.
