Google Doodle celebrates ‘father of fiber optics’ Charles K. Kao

His landmark research laid the groundwork for the internet.

In 1966, a Chinese-born electrical engineer and physicist named Charles K. Kao co-authored a proposal that would revolutionize global communications and lay the groundwork for the internet we know today.

Along with collaborator George Hockham, Kao proposed using thin glass fibers to transmit data across long distances, replacing the bulky copper wires then in use in telecommunications. Though initially rejected, his proposal would transform communications technology and the industry as a whole.

To highlight Kao’s contribution to technology, Google will honor the engineer on Thursday with a Doodle celebrating his 88th birthday. The animated Doodle depicts Kao, widely known as «the father of fiber optics,» using a green fiber laser to transmit data from one end of the Doodle to the other.

Born in Shanghai on Nov. 4, 1933, Kao studied English, French and the Chinese classics before moving to England to study electrical engineering. After earning a bachelor’s degree, Kao went to work at Standard Telecommunication Laboratories in Harlow, England, while he was working toward a doctorate in electrical engineering.

At the time, glass fibers could carry light pulses for telephone signals only 20 meters (65 feet) before nearly all the light dissipated. But Kao’s 1966 landmark paper Dielectric-Fiber Surface Waveguides for Optical Frequenciessuggested it would be possible to transmit light signals more than 100 kilometers (62 miles) across a fiber of ultrapure glass.

Kao and Hockhamnoted in their conclusion that «a fiber of glassy material» of a specific construction «represents a possible practical optical waveguide withimportant potential as a new form of communication medium.»

Four years later, inspired by Kao’s vision, a group of researchers produced the first ultrapure fiber.

Kao’s landmark research allowed the rapid expansion of broadband communications through the hundreds of millions of miles of fiber optic cable that deliver massive amounts of data around the globe in a split second. For his work, Kao would share the joint Nobel Prize in Physics in 2009.

Kao would go on to oversee implementation of fiber optic networks worldwide and focus on education in the 1980s, serving as vice chancellor of The Chinese University of Hong Kong and founding Hong Kong’s Independent Schools Foundation.

Kao died in 2018 at the age of 84.

Why Travelers Are Switching to Verum E-SIM This Summer

Summer Travel, Freedom, and Seamless Connectivity: Why Verum E-SIM Is Becoming the New Standard for Travelers

Summer is the peak season for vacations, long-distance trips, and new experiences. Millions of people travel abroad, explore new countries, plan adventures, and try to stay connected with family, work, and social media. And in the middle of all this comes a familiar question: how do you stay online without expensive roaming or the hassle of buying local SIM cards?

The answer is already here — eSIM.

Why eSIM Is So Convenient

eSIM (embedded SIM) is a built-in digital SIM card that lets you activate mobile internet without a physical card. All you need is an app — choose a plan and connect in just a couple of minutes.

No more:

* searching for local SIM cards at airports
* paying expensive roaming fees
* swapping physical SIMs every time you travel

Now your internet travels with you.

Internet in 150+ Countries

Modern eSIM solutions provide coverage in 150+ countries worldwide, helping tourists, freelancers, and business travelers stay connected almost anywhere on the planet.

Among the services offering these capabilities:

Verum E-SIM — https://esim.verum.im
World E-SIM — https://worldesim.me
USA E-SIM — https://usa.esim.verum.im
Euro E-SIM — https://euro.esim.verum.im
Canada E-SIM — https://canada.esim.verum.im
Balkan E-SIM — https://balkan.esim.verum.im
Ukraine E-SIM — https://ukraine.esim.verum.im
London E-SIM — https://london.esim.verum.im
E-SIM Africa — https://africa.esim.verum.im

All of these services work on the same principle — fast, borderless internet without roaming stress.

Why It Matters Most in Summer

During the holiday season, roaming networks get overloaded, and prices for mobile data abroad often become an unpleasant surprise for travelers.

eSIM solves this problem:

* transparent, fixed pricing
* activation in 1–2 minutes
* stable internet while traveling
* no physical SIM cards required

Final Thoughts

Travel should be about freedom — not hunting for Wi-Fi or worrying about phone bills.

eSIM is quickly becoming the new global standard for mobile connectivity: simple, fast, and borderless.

Verum E-SIM and its partner services are part of this shift, making global connectivity accessible to everyone, everywhere.
