This week's 5 AI-chip breakthroughs, in plain English

Oct 28, 2026. Light-powered chips, memory tricks, and why glass is the new gold. Which companies around the world could win or lose?

⏱️ TL;DR: the 60-second version

The big idea: AI's biggest problem isn't thinking fast. It's moving data fast enough, and this month's money and science went there.
Closest to real money: new ways to build chips with glass bases and "chip glue" (Applied Materials + Besi). Score 7/10.
Most surprising: startup Volantis already has 26 patent filings for moving memory using light.
Smart move: IBM posted a science paper and also filed a patent on the same idea, with the same team.
India: CG Power and Kaynes run chip-packaging plants that are already producing.

Scores are our judgment. Not investment advice.

💡 Did you know? A modern AI chip package can hold several chips plus stacks of memory, and it gets so big and hot that today's plastic-like bases can warp. That's why glass is in the news.

Ready-o-meter

How close is each idea to a real product? 1 = lab dream, 10 = on store shelves.

Our estimate

Glass bases + chip glue

7 — being sold/tested

Volantis light memory

Neurophos light chip

200G light switch

IBM memory trick

3 — lab only

1. Neurophos: a computer chip that thinks with light

What if your AI chip did its math with light instead of electricity?

🧠 Think of it like this: Today's chips are like a crowded highway of tiny cars (electrons) that heat up the road. Neurophos wants to swap the cars for flashlight beams, which are faster, cooler and can cross each other without crashing.

What it isA startup building an "optical" chip (photonics) for AI math. MIT researchers are now testing it on real problems (Oct 21).

Why you should careElectricity bills are the biggest cost of running AI. The company says its approach could use about 50x less (its own claim, not tested yet).

What to watchFirst real systems are planned for 2028. Watch for big chipmakers partnering with it.

Ready-o-meter: 4/10 (our judgment)

The proof (facts and sources)

Patents (checked): US 11,120,332 B2 (2021), US 11,843,182 B2 (2023), WO 2021/026152 A1, EP 4007888. Owner: Neurophos. First filed 2019.
Size claim: Its light switches are about 10,000x smaller than older designs, with millions on a 5x5 mm chip (company claim).
Stock: Neurophos is private. GlobalFoundries (GFS) is linked only through a conference talk.
Source type: University news plus patent records.

2. Volantis: moving memory at the speed of light

Can a startup with 26 patent filings break AI's biggest traffic jam?

🧠 Think of it like this: An AI chip is like a genius chef with a tiny pantry far away. Every ingredient trip wastes time. Volantis wants to build a light-speed conveyor belt straight from a giant pantry to the stove.

What it isA startup building a light-based interposer that links huge memory to AI chips.

Why you should careAI chips often sit idle waiting for data (the "memory wall"). Fixing that could change who sells memory, like today's HBM.

What to watchA first working product is about 12–18 months away, according to reports. Watch for funding news and new patent grants.

Ready-o-meter: 4/10 (our judgment)

The proof (facts and sources)

Claims: Up to 10 TB of memory at up to 240 TB/s per chip package (The Register, Oct 5). Earlier, the company claimed 1 pJ/bit links. These are company claims.
Patents (checked): 26 published US applications and 3 grants (latest Aug 25, 2026). For example US 2026/0119385 A1, US 2026/0121756 A1, US 2026/0219465 A1.
Stock: Private. No listed partner named.
Source type: Press interview, checked against patent records. No peer-reviewed paper found.

3. IBM: storing many things in one memory spot

What if one parking space could hold several cars at once, and you could still drive each one out?

🧠 Think of it like this: Normally each memory cell holds one item, like one book per shelf slot. IBM layered several items into the same slots, like overlapping see-through pages, and could still read each one back.

What it isA new IBM trick, posted on arXiv (2610.26118), that stacks many pieces of AI data into one memory chip and does the math right where the data lives.

Why you should careMore AI memory without more chips could mean cheaper, smaller AI hardware.

What to watchIt's a lab prototype with no product plan yet. Watch whether IBM uses it in its own AI chips.

Ready-o-meter: 3/10 (our judgment)

The proof (facts and sources)

Result: Tested on a real prototype chip, using data from shopping-recommendation and chatbot AI models. Accuracy was about as good as normal software.
Patents (checked): US 2026/0291719 A1 (published Sep 24, 2026), owned by IBM, with the same team as the paper. Earlier related patent: US 10,678,885 B2 (IBM).
Stock: IBM (IBM). Related research by Micron (MU) staff: arXiv 2610.20359.
Source type: Science preprint plus patent application.

4. The light switch that sends 200 billion bits a second

How do you send 200 billion bits a second through something thinner than a hair?

🧠 Think of it like this: Think of a traffic light that blinks so fast it can send a whole movie in a blink, while using about as much energy as a tiny static spark.

What it isA tiny silicon part (320 µm, about 3 hairs wide) that turns electric signals into light signals, from a study in Nature Communications (Oct 22).

Why you should careIt sends data faster using less power and fewer extra chips. That helps put light links inside chip packages (co-packaged optics).

What to watchIt's still a lab device. Watch for chip companies licensing it.

Ready-o-meter: 4/10 (our judgment)

The proof (facts and sources)

Result: 140 Gb/s at 26 femtojoules per bit (a tiny amount of energy); 200 Gb/s with extra signal clean-up.
Patents: None from this research group were checked this week. Check before relying on it.
Who: The paper names no company selling it.
Source type: Peer-reviewed science journal.

5. Glass and 'chip glue': the breakthrough closest to your wallet

Why are the world's biggest chipmakers suddenly obsessed with glass?

🧠 Think of it like this: Today's chip bases are like plywood: they bend when hot and heavy. Glass is like granite, flat and steady, so you can build a bigger 'house' of chips on top. Hybrid bonding is like welding Lego bricks together so tightly there's no gap at all.

What it isTwo upgrades to how chips are put together: glass bases instead of plastic ones, and hybrid bonding.

Why you should careThis is already being sold and tested by customers, so it is the most likely of this week's five to show up in company earnings soon.

What to watchApplied Materials and Besi tool orders, and Samsung Electro-Mechanics' glass line (target end-2027).

Ready-o-meter: 7/10 (our judgment)

The proof (facts and sources)

Facts: Applied Materials and Besi expanded their partnership (Oct 1). Their joint 'Kinex' machine is on sale. Samsung Electro-Mechanics' glass bases are being tested in real chip packages. BOE's 24-layer glass bases are in AI-chip trials.
Patents (checked): US 12,550,662 B2 (granted Feb 10, 2026) and US 12,538,855 (Jan 27, 2026), both owned by Applied Materials.
Stocks: AMAT (Nasdaq), BESI (Euronext Amsterdam). Samsung Electro-Mechanics and BOE are listed in Korea and China (tickers not checked).
Source type: Company news, product page, patent grants.

💡 Did you know? A patent is public. Anyone can read what a company is planning, often years before it shows up in a product. That's one of the 'radar signals' we look for.

Winners and losers by region

The USA looks set to gain most this week. South Korea's memory makers face some risk.

Our judgment: average of the company scores

🇮🇳 The India angle

Only companies with a link we could confirm in a source

Company	Stock code	What they do	Source
CG Power and Industrial Solutions	NSE: CGPOWER	CG Semi chip-packaging plant in Sanand, ₹7,584 cr, with Renesas and Stars; producing since mid-2026	pib.gov.in; DSCI report
Kaynes Technology India	NSE: KAYNES	Kaynes Semicon chip-packaging plant, ₹3,307 cr; producing since Mar 31, 2026	pib.gov.in; genvest.ai
SPEL Semiconductor	Listed, small company	Older-style chip assembly and testing	genvest.ai
Tata Electronics	Not listed	Assam packaging plant (₹27,120 cr) and Dholera chip factory with PSMC, both being built	pib.gov.in; DSCI

Careful: look-alikes. Owning Tata Technologies or Tata Elxsi stock does not mean you own Tata Electronics' chip plants. One research firm (Equirus) rates CGPOWER and KAYNES "Reduce" (Business Standard). No Indian listed company was linked to light-based computing or compute-in-memory.
