However, available optical power of these sources is not as high as in traditional illumination sources and hence a need of increasing this power is critical. An alternative to developing higher optical power lasers is the development of optical power aggregation optical modules, which can combine laser beams with minimum loss. Coherent and incoherent techniques have been proposed and implemented each with its advantages and disadvantages. No all-in-one solution exists and careful evaluation of the application must be performed to provide optimum performance. Some of these approaches are hardware intensive, sensitive to misalignments, costly and make use of closely spectrally separated (e.g., different wavelength) optical beams. However, there are applications, where the multiple optical beams combined must be of the same wavelengths and the aforementioned approaches are not adequate. In this presentation, we will describe an optical power aggregation technique for visible light applications such as illumination, displays and signage. First, we will discuss several coherent and incoherent beam combining techniques and present their advantages and disadvantages. Then, we will focus on the scalable, pay as you grow fiber-optic based system that can be used in these high color saturation, high contrast applications.]]> http://www1.cuny.edu/mu/cat/2012/11/07/next-webinar-scalable-power-aggregation-for-illumination-displays-and-signage-on-november-29-at-200pm/feed/ 0 http://www1.cuny.edu/mu/cat/2012/10/26/national-research-council-report-calls-for-%e2%80%9cnational-photonics-initiative%e2%80%9d/ http://www1.cuny.edu/mu/cat/2012/10/26/national-research-council-report-calls-for-%e2%80%9cnational-photonics-initiative%e2%80%9d/#comments Fri, 26 Oct 2012 16:08:58 +0000 kmurphy http://www1.cuny.edu/mu/cat/?p=77 http://www1.cuny.edu/mu/cat/2012/10/26/national-research-council-report-calls-for-%e2%80%9cnational-photonics-initiative%e2%80%9d/feed/ 0 http://www1.cuny.edu/mu/cat/2012/10/26/conference-for-pioneering-photonics-institute-celebrates-30-years-of-innovation/ http://www1.cuny.edu/mu/cat/2012/10/26/conference-for-pioneering-photonics-institute-celebrates-30-years-of-innovation/#comments Fri, 26 Oct 2012 16:00:38 +0000 kmurphy http://www1.cuny.edu/mu/cat/?p=67 http://www1.cuny.edu/mu/cat/2012/10/26/conference-for-pioneering-photonics-institute-celebrates-30-years-of-innovation/feed/ 0 http://www1.cuny.edu/mu/cat/2012/03/02/41/ http://www1.cuny.edu/mu/cat/2012/03/02/41/#comments Fri, 02 Mar 2012 19:40:10 +0000 kmurphy http://www1.cuny.edu/mu/cat/?p=41 http://www1.cuny.edu/mu/cat/2012/03/02/41/feed/ 0 http://www1.cuny.edu/mu/cat/2011/06/24/phoebus-optoelectronics-llc-chosen-as-%e2%80%9cinnovation-economy%e2%80%9d-success-story/ http://www1.cuny.edu/mu/cat/2011/06/24/phoebus-optoelectronics-llc-chosen-as-%e2%80%9cinnovation-economy%e2%80%9d-success-story/#comments Fri, 24 Jun 2011 17:16:55 +0000 kmurphy http://www1.cuny.edu/mu/cat/?p=33 http://www1.cuny.edu/mu/cat/2011/06/24/phoebus-optoelectronics-llc-chosen-as-%e2%80%9cinnovation-economy%e2%80%9d-success-story/feed/ 0 http://www1.cuny.edu/mu/cat/2011/02/07/center-for-metamaterials-iucrc-awarded-cuny-named-lead-university/ http://www1.cuny.edu/mu/cat/2011/02/07/center-for-metamaterials-iucrc-awarded-cuny-named-lead-university/#comments Mon, 07 Feb 2011 19:44:02 +0000 jrome http://www1.cuny.edu/mu/cat/?p=7 http://www1.cuny.edu/mu/cat/2011/02/07/center-for-metamaterials-iucrc-awarded-cuny-named-lead-university/feed/ 0 http://www1.cuny.edu/mu/cat/2011/02/07/cuny-cat-city-college-corning-a-winning-combination/ http://www1.cuny.edu/mu/cat/2011/02/07/cuny-cat-city-college-corning-a-winning-combination/#comments Mon, 07 Feb 2011 19:43:18 +0000 jrome http://www1.cuny.edu/mu/cat/?p=5 http://www1.cuny.edu/mu/cat/2011/02/07/cuny-cat-city-college-corning-a-winning-combination/feed/ 0 http://www1.cuny.edu/mu/cat/2011/02/07/cuny-cat-national-science-foundation-plan-center-for-metamaterials/ http://www1.cuny.edu/mu/cat/2011/02/07/cuny-cat-national-science-foundation-plan-center-for-metamaterials/#comments Mon, 07 Feb 2011 17:47:51 +0000 jrome http://www1.cuny.edu/mu/cat/?p=9 http://www1.cuny.edu/mu/cat/2011/02/07/cuny-cat-national-science-foundation-plan-center-for-metamaterials/feed/ 0 http://www1.cuny.edu/mu/cat/2011/02/07/painting-by-numbers-to-snap-a-statistical-portrait-of-america-2/ http://www1.cuny.edu/mu/cat/2011/02/07/painting-by-numbers-to-snap-a-statistical-portrait-of-america-2/#comments Mon, 07 Feb 2011 16:51:58 +0000 jrome http://www1.cuny.edu/mu/cat/?p=14 http://www1.cuny.edu/mu/cat/2011/02/07/painting-by-numbers-to-snap-a-statistical-portrait-of-america-2/feed/ 0
