PICs are deployed in scientific and technical applications including automobiles, medical diagnostics, sensors, telecommunications, etc.
The development of wireless and radio technology has led to the use of PICs and optical fibers for data transmission.
Photonic integrated circuits are used in data centers and telecommunication systems, among other things
Photonic integrated circuits (PICs) are extensively used in automotive, medical, and communication systems. Their low cost, size, weight, power consumption, and high efficiency are significant factors that have led to their widespread use. A new generation of application-specific PICs (ASPICs) are being deployed in the market as well. In this article, we will explore the broader spectrum of photonic integrated circuit applications.
Photonic Integrated Circuits
Photonic integrated circuits (PICs) are system-on-chips that operate depending on the movement of the photons. They perform intended tasks using components such as optical amplifiers, photodetectors, multiplexers, filters, switches, etc.
PICs are different from normal electronic integrated circuits (EICs) on various levels. The primary difference is the type of raw material used to fabricate PICs. It's not silicon, as we see in EICs; instead, it can be Ⅲ-V materials, silica-on silicon, or lithium niobate.
The performance of PICs is also different from EICs in aspects such as size, speed, power efficiency, bandwidth, etc. Most of these differences arise from the operation based on photons in the PIC, the counterpart being electrons in the EIC. As photons are being utilized, components are mostly optical-based, such as optical lasers, optical amplifiers, attenuators, etc.
Advantages of Photonic Integrated Circuits
PICs rule the electronics market, as they are capable of performing functions that traditional EICs can’t. However, there is no competition between PICs and EICs, as they are complementary. There are applications where PICs and EICs are integrated to perform specific tasks.
