*** 9632300 Tavlykaev This STTR Phase I project will develop a waveguide grating filter device with enhanced performance that can meet the needs of most complex WDM systems. This filter will then be coupled to an external laser source to form a hybrid optical module with tunable wavelength for a number of practical applications. This new technology, developed in conjunction with the University of Florida, will then be transferred to Advanced Photonics Technology Inc. for further refinement to a precommercial level. Wavelength-selective filters in the integrated-optic embodiment are the most promising candidates for deployment in Wavelength-Division-Multiplexed networks. A waveguide grating filter appears to be very promising on account of its extreme wavelength sensitivity and compactness. However, the performance of practical devices has thus far been severely limited by the lack of high-reflectance waveguide gratings. The unique feature of the proposed effort in achieving high-reflectance gratings is the use of a Silicon overlayer to substantially perturb the mode index of an optical waveguide underneath it without adding an additional mode loss. Silicon has been selected on account of its large refractive index, processibility, and low cost. The primary commercial application of waveguide grating filters is in Wavelength-Division-Multiplexed networks. Another most important application is the development of compact and efficient waveguide lasers and amplifiers. ***

STTR第一期项目将开发具有增强性能的波导光栅滤波器器件，可以满足大多数复杂WDM系统的需求。然后将该滤波器耦合到外部激光源，形成具有可调谐波长的混合光模块，用于许多实际应用。这项新技术是与佛罗里达大学联合开发的，随后将转移给Advanced Photonics technology Inc.进行进一步改进，以达到商业化前的水平。集成光实施例中的波长选择滤波器是在波分复用网络中部署的最有希望的候选者。波导光栅滤光片由于其极高的波长灵敏度和紧凑性而显得非常有前途。然而，到目前为止，由于缺乏高反射波导光栅，实际设备的性能受到严重限制。在实现高反射率光栅方面所提出的努力的独特之处在于使用硅覆盖层来大幅干扰其下方光波导的模式指数，而不会增加额外的模式损失。硅由于其折射率大、易加工和成本低而被选择。波导光栅滤波器的主要商业应用是在波分复用网络中。另一个最重要的应用是紧凑和高效的波导激光器和放大器的发展。＊＊＊
