Scalable Power Aggregation for Illumination, Displays and Signage
Nicholas Madamopoulos, Ph.D.
Department of Electrical Engineering, Grove School of Engineering, The City University of New York
Recent developments in reliability, yield and mass production of lasers have increased the interest in using lasers as illumination sources. 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.
