We compute and compare the coupling coefficient from the extracted optical power for coupled photonic crystal VCSEL arrays. Increasing cavity diameter is found to increase the coupled output leading ...

Laser speckle caused by high coherence severely affects the image quality. The traditional optical approaches cannot effectively suppress speckles without compromising the coherence of the laser in ...

And the dream gig comes with more than just access to cool new product: For his 50th birthday, Tudor seems to have gifted ...
