Recent developments involving holographically patterned photosensitivity in glass-based optical waveguides developed by our group can be extended to fabricate complex two-dimensional structures including planar waveguide photonic bandgap devices for applications in telecommunications, sensing and signal processing. These will include novel grating-array based 2-D DFB lasers and filters in rare-earth doped planar waveguides. Novel etching techniques to be used to enhance index contrast, as well as to characterise such devices, will be developed based on our recent observation of hydrogen-enhanced etching of glass. Such methods could potentially be applicable to not only photonic technologies but also semiconductor lithography of oxides.

我们小组最近在基于玻璃的光波导中开发的全息图像化光敏性可以扩展到制造复杂的二维结构，包括用于电信，传感和信号处理的平面波导光子带隙器件。这些将包括基于新型光栅阵列的二维DFB激光器和稀土掺杂平面波导中的滤波器。基于我们最近对氢增强玻璃蚀刻的观察，将开发用于增强折射率对比度以及表征此类设备的新型蚀刻技术。这种方法不仅可以应用于光子技术，还可以应用于氧化物的半导体光刻。
