VCSELs rev up for life in the fast lane
Multi-junction vertical-cavity surface-emitting lasers are likely to displace LEDs and edge-emitting lasers in sensing, finds Andy Extance

Coherent has today decided to accept II-VI's offer and will pay Lumentum the $217.6 million termination fee

Although a lot of outstanding results have been demonstrated in terms of energy and power scaling of ultrafast lasers in the past 20 years, the technology has now reached a certain level of maturity, believes Simonette Pierrot, principal laser engineer at Lumentum.
‘In my opinion the focus in the pulsed laser field will now be less about opening the way to new performance such as shorter pulse or higher energy, more about stabilizing it and making it manufacturable in high volume,’ she said.
OQE will supply epiwafers supporting 3D sensing, lidar for automotive and optical networking applications
15 finalists have been selected by a panel of expert judges for the award, which will be presented at Laser World of Photonics later this month
The award recognises Lumentum’s achievements in successfully integrating efficiency and effectiveness into its manufacturing processes
The partners will incorporate VCSEL array light sources into lidar to improve its cost and scalability
The addition of NeoPhotonics is designed to expand Lumentum's opportunity in the optical components market, particularly for cloud and telecom network infrastructure
On 18 March, Coherent confirmed receipt of a revised acquisition proposal from II-VI. Lumentum now has until the end of the day to make a revised offer.
As microscopes become ever more powerful, a growing band of businesses are racing to make the latest technologies more accessible and more affordable, reports Rebecca Pool

(b) Crystal with a linear confining centre where waves can propagate in one dimension, analogous to an optical fibre. (c) Crystal with a planar confining centre where waves can propagate in two dimensions, analogous to a 2D electron gas. (Image: Vos et al.)
