Lightwave Logic Inc., a company focused on the development of next generation photonic devices and non-linear optical polymer materials systems for high speed fibre-optic data communications and optical computing, has integrated its proprietary Perkinamine chromophore technology, with other chromophores based in part on aspects of proprietary, in-licensed technologies. This has resulted in a powerful and durable nonlinear organic electro-optical (EO) material that will be used in photonic device development and is based on its multi-chromophore approach that allows two or more chromophores to work in concert, the company stated.

Starting with the fundamental underpinnings of Lightwave's proprietary Perkinamine technology, the Lightwave Logic research scientists have found that by combining various Perkinamine chemical compounds with certain aspects of in-licensed chromophore portfolios, the total chromophore concentration in a host polymer system can be dramatically improved. The company intends to further validate this performance in prototype photonic devices. Key results will be shared with interested industrial partners.

Lou Bintz, VP of product development stated, "This multi-chromophore system has achieved a 50 per cent increase in chromophore concentration, leading to higher electro-optical activity when compared to an equivalent single chromophore system. It does not cause the high chromophore density loading issues such as reduced effective electro-optic activity due to a non-uniform concentration of chromophore in the polymer host. For the past several months we have consistently witnessed amazing durability and poling stability (chromophore alignment) in thin film measurement tests in our new Longmont, Colorado device fabrication and testing facility. Repeated, multi-point measurements show twice the electro-optic effect of Lithium Niobate with excellent durability."

Tom Zelibor, chair and CEO of Lightwave Logic stated, "Since developing this new capability, our corporate focus has been to expand our portfolio of EO materials, not to replace our core Perkinamine family of chromophores, but to work with them adjunctively.

"These results are vitally important to our commercialisation efforts and validate our scientific approach. This creates a myriad of market opportunities due to almost infinite potential combinations of molecules and parts of molecules with unique properties to address distinct market opportunities. We will soon put the material into proprietary, advanced design photonic devices together with the Guided Wave Optics Laboratory in the University of Colorado.

"Malachite is undoubtedly the most durable nonlinear organic material system we have ever synthesised that also possesses high electro-optic efficiency, and the ability to work in ambient conditions. It is designed to enable a data communications transceiver to function inside the data centre. We intend to satisfy the enormous and as yet unfulfilled demand for 100Gb/s data rates inside these massive and complex facilities. We are already working on a next generation Malachite material system to target a different application."
