Reinventing the laser diode: free public lecture by Professor Richard Hogg


  • Professor Richard Hogg joined Aston University in spring 2023 
  • His inaugural lecture is about laser diodes, the tiny components that are a vital part of everyday life 
  • The free event will take place on Tuesday 28 November.

The latest inaugural lecture at Aston University will explore the laser diode and what’s in store for it in the future.

Professor Richard Hogg will explain how his future research might make laser diodes do some of the things that they currently can’t do.

The laser diode turned 61 years old this month and the tiny components are a critical part of everyday life. Professor Hogg said: “They are now at the heart of the continuous transformation of society. 

“They transmit data to allow instantaneous, ubiquitous communication and data access. 

“They allow light to be used for cutting and welding, for sensing and imaging, for displays and illumination, and data storage. 

“And in the guise of a laser pointer they can even be used to entertain your cat!” 

He will discuss different classes of laser diode and their operation and applications.

Professor Hogg joined Aston University in spring 2023 and is based at Aston Institute of Photonic Technologies (AIPT). It is one of the world’s leading photonics research centres and its scientific achievements range from medical lasers and bio-sensing for healthcare, to the high-speed optical communications technology that underpins the internet and the digital economy.

The professor is also chief technology officer at III-V Epi, which provides compound semiconductor wafer foundry services. 

The free event will take place on the University campus at Conference Aston, on Tuesday 28 November from 6pm to 8pm and will be followed by a drinks reception. It can also be viewed online.

About Aston University
For over a century, Aston University’s enduring purpose has been to make our world a better place through education, research and innovation, by enabling our students to succeed in work and life, and by supporting our communities to thrive economically, socially and culturally.

Aston University’s history has been intertwined with the history of Birmingham, a remarkable city that once was the heartland of the Industrial Revolution and the manufacturing powerhouse of the world.

Born out of the First Industrial Revolution, Aston University has a proud and distinct heritage dating back to our formation as the School of Metallurgy in 1875, the first UK College of Technology in 1951, gaining university status by Royal Charter in 1966, and becoming The Guardian University of the Year in 2020.

Building on our outstanding past, we are now defining our place and role in the Fourth Industrial Revolution (and beyond) within a rapidly changing world.
