Eric's paper is chosen for the cover of Applied Optics

A paper recently published in Applied Optics by Eric (Fan Yang) has been selected to feature as the cover image for that issue. Eric's paper - Fast precalculated triangular mesh algorithm for 3D binary computer-generated holograms - demonstrates a new technique for rapid 3D hologram generation. This new triangular mesh system greatly enhances the hologram design process and allows for better GPU acceleration using standard CUDA based graphics cards.

Color holograms using plasmonic nanoparticles!

A paper recently published in PNAS by Yunuen Montelongo and colleagues of the CMMPE group has demonstrated, for the first time, a two colour hologram patterned in plasmonic silver nano rods (or antennae). The rods were fabricated on the nanometre scale using ebeam lithography. The dimensions of rods determines which wavelength of light can be used to excite a surface plasmonic resonance. This resonance is then used to diffract the light into a pre-determined image. In this device, two separate holograms were encoded using two different lengths of nano-rod, giving separate holofraphic replay images depending on the wavelength of the illumination.

Excellent results for CMMPE at the 2014 BLCS Meeting

The CMMPE Group was very well represented at this years BLCS annual meeting in Durham. Aside from the usual drinking and socialising, there were some excellent papers and posters given as part of a very stimulating conference line up. The meeting was ample proof that there is still a vibrant and diverse liquid crystal community within the UK. Subjects spanning theory to experiment from twist bend phases to Flynn's (CMMPE alumni) classic paper on the true diversity of chiral materials still waiting to be discovered.

The CMMPE attendees were also showered with much deserved acolades:

The best student presentation prize went to Rachel Hyman for her work ‘Polarisation independent phase-modulation of light using polymer-stabilised blue phase liquid crystals’ which is a major step forward in finding an elusive high speed phase modulation material.

The poster prize was won by Calum Williams for his epic ‘Tunable multifunctional nanostructured holograms using liquid crystals’ which shows the true diversity of different mechanisms that can be harnessed through liquid crystals.

And Tim Wilkinson was awarded the 2014 Hilsum Medal

Flynn Castle's paper at SID's "Display Week 2009" symposium highlighted as "notable paper"

The April 2009 edition of the SID's publication "Information Display" previews the forthcoming SID symposium, "Display Week 2009". On page 17, it highlights CMMPE research, to be presented by Flynn Castles, as a "notable paper" of interest. The paper describes some of the modelling work from his PhD (supervised by Harry Coles) on the flexoelectro-optic effect, and how it can provide a fast switching mechanism suitable for use in field-sequential, color, full-motion video displays.

CMMPE bistable displays research highlighted on SPIE newsroom pages

The SPIE Newsroom pages (23rd April, 2009) feature an article highlighting recent CMMPE research. The research, carried out by Dr. Damian Gardiner, Dr. Stephen Morris and Prof. Harry Coles, demonstrates how novel smectic-A materials can be used for low power consumption, high efficiency, multi-stable smart windows/glazing. The news report is in response to a recent publication on the same subject, published in Solar Energy Materials and Solar Cells.

CMMPE LC lasers research highlighted in Nature Photonics & Dept. of Engineering website

The April 2009 edition of Nature Photonics features an "out of the lab" news article focussing upon liquid crystal lasers research. It highlights CMPPE's research on simultaneous red, green & blue polychromatic liquid crystal laser arrays, and represents the 2nd occasion that Nature Photonics has highlighted CMMPE's LC lasers research. Furthermore, the Cambridge University Engineering Department's website front-page currently features a news article highlighting the same research. These news articles are in addition to the recent article in Laser Focus World (see CMMPE news item 09/01/09), which also highlights the same work.
