Technology of the 21st century.
Semiconductors are getting a lot of attention. In conventional semiconductor chips, electrons are used for transmitting and processing signals. We're using Integrated circuits (ICs), or microchips, everywhere. These circuits are essential parts of countless modern technologies from medical devices to smart watches, computers to spacecraft. They consist of a set of electronic components such as transistors, resistors, and amplifiers on a semiconductor wafer. But, this is energy consuming, it requires expensive materials and can't follow higher data speeds needed in the future.
So, what's next? Why not using photons (light) instead of electrons for computing and signal processing? What is faster than light? Much of the functionality of these conventional, Integrated Circuits can be replaced by working with light instead of electrons. To be able to use light, we need a new type of integrated circuit, called Photonic Integrated Circuits (PIC's), with photonic components including lasers (used to generate light signals that represent 0's or a 1's) and waveguides (used to guide light signals) onto a single chip. These PIC's are often also called "silicon photonics", because silicon is used as a medium.
In the beginning this was all prototyping, lots of trail and error, because light isn't as easy as electrons. It has to be reflected using mirrors and guided trough the circuit without unwanted light losses due to absorbing along the way.
During the past 2 decades, our world's smartest engineers have been really busy. Today we have developed fully functional PIC's, already in the market. So, we CAN use light. It's perfectly possible. But why doesn't people know this? That's because the assembly of a PIC is difficult because it requires a lot of labor, it's all hand work, and this manufacturing issue leads to scalability issues and, this make PIC's more expensive (purchase price) than IC's. For example Intel is doing it this way and already shipping high volumes of PICβs.
But guess what, there has been developed kind of 3D printing techniques. A wafer-scale assembly, with flip-chipping techniques. So these components get flip chipped on a wafer hundreds at a time. These techniques reduce time and costs (-40%) and make PIC's much more attractive. The PIC performance results are superior. Completely outperforming the older PIC's and IC's. This has been done only by POET Technologies so far. Moreso, they use CMOS manufacturing mach

Because of the numerous advantages of "photons" (light) in comparison with "electrons", photonic circuits (to "use" this photons) will be implemented in almost every electronic device (datacom, 5G, LiDAR , medical devices, sensors, quantum computing, neurotrophic computing,...) and thereby replacing the old, expensive and limiting electronic structures, in the near future (couple years from today).

Just like the internet, hydrogen, electric vehicles, green stocks,...the photonic circuit market is forecasted to take off.

After years of development by a topclass highly experienced team, POET Technologies (POETF) now has the technology (the "POET interposer platform") to use photons in devices with outstanding performance, well covered by >70 patents. They also have already 4 committed customers (POET said they will announce more info soon) lots of requested samples, two design wins and a joint venture with SANAN IC for mass production soon. Nasdaq (in q4/q1) ticker "POET" is reserved. Their first market of interest is datacom.
Investment bank IBK Capital Corp: "POET is at an inflection point for rapid growth. As part of the fab-light strategy, POET will focus on growing the OI business in fast-growth, multi-billion dollar markets driven by internet traffic, datacenter development, 5G networks and the integration of photonics and network switching devices. The total available market POET is pursuing for integrated photonics is estimated to be US$20 billion by 2025. Price target: 9,56usd, 12-18 months."

If I understand correctly, most battery powered circuits use the negative side (i.e. the wires and components connected to the negative terminal of the battery) of the circuit as the "ground" when represented in diagrams, and is what the ground pin of the second kind of integrated circuit is (at least usually) connected to. Why does the first kind of IC require a "split supply" in order to work properly? Why aren't batteries considered "split supplies"?
Without a doubt its a been a wild few days. Here are some interesting events I like to share.
>Nvidia on Tuesday unveiled a new version of its GeForce RTX 3080 graphics card with 12GB of memory, a 2GB bump over the 10GB version of the RTX 3080 that came out in 2020. The upgraded 12GB RTX 3080 will be available starting today from Nvidia's partners.
>Jack Dorseyβs BLOCK is hiring Mining Experts. Moreover, according to a recent listing Block is looking to hire a custom digital design lead to join the team that will help build the βnext generationβ of microchips used to mine coins. In a series of tweets in October 2021, Block CEO Jack Dorsey touched on some of the key features that would be included in the open-source mining system based on custom silicon. βMining needs to be more distributed. The core job of a miner is to securely settle transactions without the need for trusted 3rd parties. This is critical well after the last bitcoin is mined. The more decentralized this is, the more resilient the Bitcoin network becomes,β stated Dorsey at the time
I mean... those chips are SOOO tiny! On a breadboard, for example, you need voltage dividers... or opto-isolators... or other things I don't know about. Ends up being a large device. I've scoured electronics forums, battery forums, engineering forums, and no seems to have an idea/circuit that even competes with those tiny, cheap chips. How are they doing it?
Thanks!

It is also for the physical and industry side of chips, in addition to the computing side.
Whenever you have a hardware-related post, please put a copy to that sub and also subscribe to it.
If this is wrong subreddit to tell about this incoming / nascent chip sub, then what is correct? Criteria should not be that the purviews and sets of topics should be same, but that there should be large overlap or large percentage of users in one sub would be interested about the other. Criteria should be similar to the links in the sidebar and even looser. If it is controversial or up to debate whether the recommended subreddit's purview is sufficiently related to this subreddit's purview, then that question should be left for the users. Let them make up their own mind and we can debate that question here.
Even if this subreddit is meant for discussing computing from a point of view where it does not matter whether the computing is done with special hardware or software in general-purpose CPU, integrated circuits are still a related topic.
Hello! I wished to know if anyone knows some good articles about current sensing in integrated circuits. In particular utilizing a sense resistor. The ones i've found seemed too specific. I'm not too familiar with some technical terms in english and there are really few articles about it in portuguese. Books suggestions are also welcome.
Thanks in advance!
In 1978 the contract for the Monza Sports facility was about to expire and was almost not extended due to political disputes. A new circuit was proposed which was located up to 150km away from the original circuit. The Layout featured the known Layout but replaced the Oval with a "normal" sector.
Sadly I did not find out how long this Layout was supposed to be, but the second has a scale in it which I wasn't able to read

Light is faster than electrons, it can be switched more quickly, it can be split into a broad spectrum of colours (and therefore frequencies) instantly increasing the number of signals that can be sent and it doesn't generate the same amount of waste heat as conventional IC's. Much of the functionality of these conventional, Integrated Circuits could be replaced by working with light instead of electrons. But to be able to use light, we need a new type of integrated circuit, called a Photonic Integrated Circuit (PIC).
