The potential of ultrafast laser machining for the design of integrated optical devices in ULE® glass, a material known for its low coefficient of thermal expansion (CTE), is addressed. This was done through laser direct writing and characterization of optical waveguides and through the fabrication of 3D cavities inside the glass by following laser irradiation with chemical etching. Type I optical waveguides were produced and their internal loss mechanisms at 1550 nm were studied. Coupling losses lower than 0.2 dB cm−1 were obtained within a wide processing window. However, propagation loss lower than 4.2–4.3 dB cm−1 could not be realized, unlike in other glasses, due to laser-induced photodarkening. Selective-induced etching was observed over a large processing window and found to be maximum when irradiating the glass with a fs-laser beam linearly polarised orthogonally to the scanning direction, akin to what is observed in fused silica laser-machined microfluidic channels. In fact, the etching selectivity and surface roughness of laser-machined ULE® glass was found to be similar to that of fused silica, allowing some of the already reported microfluidic and optofluidic devices to be replicated in this low CTE glass. An example of a 3D cavity with planar-spherically convex interfaces is given. Due to the thermal properties of ULE® glass, these cavities can be employed as interferometers for wavelength and/or temperature referencing.
本研究探讨了超快激光加工在 ULE® 玻璃（一种以热膨胀系数（CTE）低而著称的材料）中设计集成光学设备的潜力。具体做法是通过激光直接写入光波导并对其进行表征，以及通过化学蚀刻激光辐照在玻璃内部制造三维空腔。我们制作了 I 型光波导，并研究了其在 1550 纳米波长的内部损耗机制。在较宽的加工窗口内，耦合损耗低于 0.2 dB cm-1。然而，与其他玻璃不同的是，由于激光诱导的光致变色，无法实现低于 4.2-4.3 dB cm-1 的传播损耗。在较大的加工窗口内观察到了选择性诱导蚀刻，并发现当用与扫描方向正交线性偏振的fs激光束照射玻璃时，选择性诱导蚀刻最大，这与熔融石英激光加工微流体通道中观察到的情况类似。事实上，激光加工的 ULE® 玻璃的蚀刻选择性和表面粗糙度与熔融石英相似，因此可以在这种低 CTE 玻璃中复制一些已报道的微流体和光流体设备。本文举例说明了具有平面球凸界面的三维空腔。由于 ULE® 玻璃的热特性，这些空腔可用作波长和/或温度基准的干涉仪。
