If you haven’t heard about optical I/O yet, the big news is that you probably have at least heard a great deal about its potential for speedups and cost savings.
You can see a video of a system I/O that I wrote up some time back. It’s a prototype that I built using a laser printer, a 10:1 servo and a few small LEDs and a few cheap resistors to light up the printed circuit board.
It’s a very interesting system and I didn’t realize how small I was putting the components on. I’m sure it is a future project.
I hope you enjoy my video of it. I had to take it down because it was on to a very long video.
Let’s take a look at what the laser, the optical I/O, the servo, and the LEDs are doing over here.
Optical I/O is a technique for transmitting information over an optical communication link. In its simplest form optical I/O is the transmission of light, or some other form of light through an optical link. The light is then combined with a receiver at the other end of the link and the information is read back out by the receiver. This works well for transmitting data across multiple signals, but it’s not a very robust system as it is also susceptible to noise.
The real breakthrough, however, is when you can combine a laser with the optical receiver. The idea is, instead of sending light, you send a laser beam, and then the optical receiver can do some fancy processing on the laser beam to figure out where it came from and therefore where the light is coming from. This is the idea behind the technique used in integrated optoelectronic (IOE) systems that I described way back.
In optical IOE systems, instead of the optical receiver having to work with light it can work with the output of the laser. This provides a huge speed boost and cost savings compared with the typical I/O system.
Silicon photonics for distributed and hybrid systems.
Article Title: Silicon photonics for distributed and hybrid systems | Computer Hardware. Full Article Text: The silicon photonics community has long been interested in the ability to build distributed and hybrid systems. Today, this research area is receiving attention due to the development and implementation of silicon photonics and silicon nanoelectronics. A new generation of silicon photonics systems will use silicon based quantum chips to build these devices. As silicon photonics is mature technology, it will be very challenging for people to build distributed and hybrid systems using silicon based electronics and photonics. There are numerous advantages to using silicon photonics to build distributed and hybrid systems. 1) High carrier mobility devices with a low threshold voltage. Recent work has demonstrated that it is possible to integrate silicon photonics based devices with silicon based electronics and this work will continue to grow. A key element in this technology is carrier mobility. The current work has demonstrated that it is possible to integrate silicon-based electronics that can operate at less than 200 mV with a silicon photonics cell at less than 1 V. So many different applications have been realized which include but are not limited to, cell phone, mobile phone, automotive, industrial, commercial, and automotive use cases. 2) Low power requirements. Photonics based systems have shown that it is possible to integrate them with silicon based electronics, and this has the ability to achieve low consumption devices such as solar cells and photodetectors. So many different commercial and industrial devices can now be realized using this technology. 3) It is possible to achieve submicron device dimensions. Smaller device dimensions, particularly at the metal-semiconductor-metal (MSM) level, has resulted to devices on a submicron level. In addition, it has enabled the creation of new types of devices by creating new layers such as nanowire based devices. So many new device types have been realized. 4) It is possible to create devices in other materials, including III-V materials, as they are becoming more mature. So new materials such as silicon-on-insulator (SOI) have been considered. Silicon-on-insulator has the ability to operate at lower voltages, typically 0. So as this technology matures so many new devices come to the forefront. 5) Many devices that are now being developed can be realized at a reduced cost. Many of these devices are very inexpensive to make.
PCI-Express vs. CXL over PCI-Express
Article Title: PCI-Express vs CXL over PCI-Express | Computer Hardware.
“I am the only one who should be giving up his job to give my life. That’s what should be my message to all of you.
This is to say to all of you all in the Computer Hardware Industry, that although I am not writing to you all in the Computer Hardware Industry, I still feel the need to tell you that I am giving up my job for the cause of Computer Hardware.
I am giving up my job for a cause which everyone should consider, and which has many facets, but which is most commonly referred to as the “PCI-Express vs. CXL over PCI-Express” issue.
I am giving up my job to promote the idea that CXL over PCI-Express is the superior solution, and I have no doubt whatsoever that I will accomplish that, and that most of the companies in the industry will do that.
I must thank this article for its very good advice, and I shall certainly take this article with me into all parts of my career.
“In order to have the best PCI-Express experience, and to have the best PCI-Express experience with the best support, you should invest in CX.
I believe that this statement by Dan Lutkin, is wrong.
CX is a great solution, but not the solution on which I have spent my most valuable years in the Computer Hardware Industry.
I have spent years, and thousands of dollars, learning the computer hardware on which I was using my skills in, and which I was able to use to advance the software industry, and to develop an understanding of the computer hardware which now provides me with the opportunity to give something back to society through my business.
I will miss not having the opportunity to work for a company which is able to provide me with a much better experience, both in technology, and in business, than I had with the company which I had worked for for the last 10 years, with my entire career.
I spent an enormous amount of money, and an enormous amount of time, in the company which I was working for and I will be leaving it for the time being.

Tips of the Day in Computer Hardware
When I was in college, a young friend from a great family (who I would later marry) was in my first year of college, taking a course in a computer science class I was enrolled in. It was a course she was taking, and she had been very busy working with computers, with programming. She had been programming with computers for many years, and her life was completely different than mine in that she was in college, with a full social life and all that, and I was a student who had gone to school all semester, with no classes, and she had some social life, but I knew that was about it.
We would talk about things we were interested in with her, about a movie she wanted to watch, or a game she wanted to play. And often she’d say, “I haven’t worked in any computer software in years. What I’m doing now is very interesting, but I’m only a sophomore. In a year or two I can probably go to grad school and get a job.
