A life with light

January of this year saw Jerry Rawls step down as chief executive of Finisar, a company he had grown from obscurity to worldwide success. He talks to Rebecca Pool about building his empire, the firm’s new CEO and a future that could include Oclaro*

What prompted you and Frank Levinson to launch Finisar in the late 1980s?

Harnessing the nonlinear communication regime

Between the covers of optical communication research journals, heated arguments have been waged, leading to ‘a stand-up row, almost’, according to Professor Polina Bayvel from University College London. The disagreements centre on whether optical fibres exhibit a ‘nonlinear Shannon limit’ to their capacity. The dispute emerges from a question that challenges the whole industry. Is the future of fibre-optic technology already facing a fundamental, impenetrable, nonlinearity obstacle? It’s a theoretical question with potentially huge practical implications.

CPR: lifesaver or liability?

Fires feature on the mainstream news with somewhat alarming regularity. From the tragedy that took place at the Grenfell tower block in the UK last year, to forest fires in warmer regions, a fire will often make headlines. Much of the aftermath of such a story generally includes speculation as to a fire’s cause, or what measures could have been implemented to either prevent the blaze entirely, or stop its spread.
