DMI-0339012This Small Business Innovation Research Phase I project proposes to design and demonstrate an athermal multiplexer based on an already existing arrayed waveguide-grating (AWG) device. AWGs are key components in wavelength division multiplexed optical networks. Temperature induced changes in the refractive index of conventional AWGs based on silica-on-silicon technology result in large shifts in the peak wavelength transmission. This necessitates the use of thermoelectric coolers and temperature sensing and compensating circuitry. A specially designed external mirror combined with a reflective AWG (R-AWG), will be used to compensate the temperature-induced index change. Differential thermal expansion of the mirror assembly rotates its reflecting surface at a constant rate with temperature. The reflective AWG-external mirror combination also allows for wavelength trimming that centers the channel wavelength at the ITU grid. The detailed rotation rate and design of the mirror will be determined by simulation and experiments. The goal of this project is to fabricate a high-performance 40-channel, 100 GHz, passive AWG device insensitive of temperature in the 0-85 degree C range. The work hopes to significantly improve the performance of DWDM-based telecommunication systems. These features hope to make the athermal reflective-AWGs proposed here attractive and commercially competitive when compared to conventional AWGs. The new approach should eliminate complex packaging and processing steps, the need for electric power and external temperature control, resulting in a more robust, easier to use, and considerably less expensive packaged device.

ESTA-0339012这个小企业创新研究第一阶段项目提出设计和演示一个无热复用器的基础上已经存在的阵列波导光栅（AWG）设备。AWG是波分复用光网络中的关键部件。温度引起的折射率的变化，在传统的AWG基于硅上二氧化硅技术的结果在峰值波长传输的大位移。这需要使用热电冷却器和温度传感和补偿电路。 一个特殊设计的外部反射镜结合反射式AWG（R-AWG），将用于补偿温度引起的折射率变化。镜组件的不同热膨胀使其反射表面随温度以恒定速率旋转。反射式AWG-外部反射镜组合还允许波长微调，将信道波长集中在ITU网格上。详细的旋转速率和反射镜的设计将通过仿真和实验来确定。本项目的目标是制作一个高性能的40通道，100 GHz，无源AWG器件的温度不敏感的0-85摄氏度的范围。这项工作有望显著提高基于DWDM的电信系统的性能。这些功能，希望使无热反射AWG这里提出的吸引力和商业竞争力相比，传统的AWG。新方法应消除复杂的封装和处理步骤，对电力和外部温度控制的需要，从而产生更坚固，更易于使用且相当便宜的封装器件。
