This SBIR Phase I research project will develop monolithic multicolor sensor array with high quantum efficiency, high speed for numerous system applications. Today's sensor arrays are designed to work either in visible or in near infrared region. None of these can provide broad spectral response (300 nm to 2500 nm). The goal is to identify suitable sensor array structures for broad range detection, with combined high quantum efficiency, and high speed. A second goal is to identify a photodiode or sensor array structure where each pixel can be addressed independently. The design, performance simulation, and also physical parameters optimization will also be carried out as a part of this research activity.The broader impact of this research is that broad spectral image sensors are required for various ground-based, air-borne, space-borne geo-science instruments for the atmospheric properties measurement, surface topography, range detection, remote sensing, and real-time monitoring of biological systems. To date, several sensors covering different spectral ranges are used for this purpose. Next generation geo-science and astronomical instrumentation require single sensor that can detect multiple spectral bands (300 to 2500 nm of wavelengths) and could be used for multiple earth-science measurements. Use of single sensor having multifunctional capability can make the instrument unusually small, light and low-power requirement.

该SBIR第一阶段研究项目将开发具有高量子效率、高速度的单片多色传感器阵列，用于众多系统应用。今天的传感器阵列被设计成在可见光或近红外区域工作。这些都不能提供广谱响应（300 nm至2500 nm）。目标是确定适合宽范围探测的传感器阵列结构，结合高量子效率和高速度。第二个目标是确定一个光电二极管或传感器阵列结构，其中每个像素可以独立寻址。设计、性能仿真和物理参数优化也将作为这项研究活动的一部分进行。本研究的更广泛影响是，用于大气特性测量、表面形貌、距离探测、遥感和生物系统实时监测的各种地基、机载、星载地球科学仪器都需要广谱图像传感器。迄今为止，有几种覆盖不同光谱范围的传感器用于此目的。下一代地球科学和天文仪器需要单个传感器，可以探测多个光谱波段（300至2500纳米波长），并可用于多个地球科学测量。采用具有多功能功能的单一传感器，可使仪器体积小、重量轻、功耗低。
