The commercial adoption of GaN-on-Si light emitting diode (LED) chip technology is lagging behind incumbent sapphire substrates due to significantly longer growth time and poorer crystalline quality. To address these challenges, we report on the grow

In display projection applications, micron scale light emitting diode (μLED) array displays present an alternative to conventional lamps as light sources, with the advantage of higher efficiency and smaller form factor (particularly if the array is

The manufacturability of blue LED structures grown on 6-inch Si (111) substrates is reported. The totally epi-structure thickness is only 3.75 μm, which allows faster epitaxy process throughput and lower manufacturing costs. Well controlled strain e

To extend the depth-of-focus of incoherent imaging systems an aspherical pupil plane element is designed to encode the incident wavefront in such a way that the image recorded by the detector can be accurately restored over a large range of defocus.

Evaluation of the electromagnetic fields diffracted from plane apertures are, in the general case, highly problematic. Fortunately the exploitation of the Fresnel and more restricted Fraunhofer approximations can greatly simplify evaluation. In parti

A quartic phase retardation function is described that reduces the variation of the intensity of the focal point of incoherent imaging systems suffering from primary third-order aberrations limited to coma and astigmatism. Corresponding modulation tr

This paper gives a review on the design and use of both amplitude filters and phase filters to achieve a large focal depth in incoherent imaging systems. Traditional optical system design enhances the resolution of incoherent imaging systems by optic
